Drivers for Large LCD Panels  
6bit RSDSTM  
Source Driver  
BU95408  
No.10043EAT04  
Description  
ROHMLCD drivers for large panels are display drivers optimized for large LCDs in a variety of applications, including  
desktop PCs, laptops, and TVs. The broad lineup is offered in low amplitude differential transmission interface type  
(RSDSTM) featuring low EMI, 6bit gradation precision, and different output configurations (720 and up) for wide compatibility.  
Features  
1) 684/690/702/720 output channels  
2) 6bit 9pair RSDSTM inputs  
3) Dot & n-line inversion available  
4) Built-in 2ch repair amplifiers  
5) γcorrection is possible  
6) Built-in input data reversing function (INV)  
7) Output voltage range: AVSS+0.1V ~ AVDD-0.1V  
8) High speed data transfer: fCLK(MAX)=85MHz  
9) Logic power supply voltage (DVDD) : 2.3 ~ 3.6V  
10) Driver power supply voltage (AVDD) : 8.0 ~ 13.5V  
11) Package: COF48

Notes for use  
1. When power is first supplied to the CMOS IC, it is possible that the internal logic may be unstable and rush current may  
flow instantaneously.  
Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of  
connections.  
2. For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal  
powering sequence and delays.  
Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of  
wiring.

Notice  
Precaution on using ROHM Products  
1. Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,  
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you  
intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport  
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car  
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or  
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.  
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any  
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific  
Applications.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor  
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate  
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which  
a failure or malfunction of our Products may cause. The following are examples of safety measures:  
[a] Installation of protection circuits or other protective devices to improve system safety  
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure  
3. Our Products are designed and manufactured for use under standard conditions and not under any special or  
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way  
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any  
special or extraordinary environments or conditions. If you intend to use our Products under any special or  
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of  
product performance, reliability, etc, prior to use, must be necessary:  
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents  
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust  
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,  
H2S, NH3, SO2, and NO2  
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves  
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items  
[f] Sealing or coating our Products with resin or other coating materials  
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of  
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning  
residue after soldering  
[h] Use of the Products in places subject to dew condensation  
4. The Products are not subject to radiation-proof design.  
5. Please verify and confirm characteristics of the final or mounted products in using the Products.  
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,  
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power  
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect  
product performance and reliability.  
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual  
ambient temperature.  
8. Confirm that operation temperature is within the specified range described in the product specification.  
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in  
this document.  
Precaution for Mounting / Circuit board design  
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product  
performance and reliability.  
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the  
ROHM representative in advance.  
For details, please refer to ROHM Mounting specification

Precautions Regarding Application Examples and External Circuits  
1. If change is made to the constant of an external circuit, please allow a sufficient margin considering variations of the  
characteristics of the Products and external components, including transient characteristics, as well as static  
characteristics.  
2. You agree that application notes, reference designs, and associated data and information contained in this document  
are presented only as guidance for Products use. Therefore, in case you use such information, you are solely  
responsible for it and you must exercise your own independent verification and judgment in the use of such information  
contained in this document. ROHM shall not be in any way responsible or liable for any damages, expenses or losses  
incurred by you or third parties arising from the use of such information.  
Precaution for Electrostatic  
This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper  
caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be  
applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron,  
isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control).  
Precaution for Storage / Transportation  
1. Product performance and soldered connections may deteriorate if the Products are stored in the places where:  
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2  
[b] the temperature or humidity exceeds those recommended by ROHM  
[c] the Products are exposed to direct sunshine or condensation  
[d] the Products are exposed to high Electrostatic  
2. Even under ROHM recommended storage condition, solderability of products out of recommended storage time period  
may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is  
exceeding the recommended storage time period.  
3. Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads  
may occur due to excessive stress applied when dropping of a carton.  
4. Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of  
which storage time is exceeding the recommended storage time period.
