74LVC16245A; 74LVCH16245A  
16-bit bus transceiver with direction pin; 5 V tolerant; 3-state  
Rev. 14 — 24 September 2021  
Product data sheet  
1. General description  
The 74LVC16245A; 74LVCH16245A is a 16-bit transceiver with 3-state outputs. The device can be  
used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables  
(1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for  
direction control. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.  
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices  
as translators in mixed 3.3 V and 5 V environments.  
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.  
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry  
disables the output, preventing the potentially damaging backflow current through the device when  
it is powered down.  
The 74LVCH16245A bus hold on data inputs eliminates the need for external pull-up resistors to  
hold unused inputs.  
2. Features and benefits  
Overvoltage tolerant inputs to 5.5 V  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low power dissipation  
MULTIBYTE flow-through standard pin-out architecture  
Low inductance multiple power and ground pins for minimum noise and ground bounce  
Direct interface with TTL levels  
IOFF circuitry provides partial Power-down mode operation  
All data inputs have bus hold (74LVCH16245A only)  
Complies with JEDEC standard:  
JESD8-7A (1.65 V to 1.95 V)  
JESD8-5A (2.3 V to 2.7 V)  
JESD8-C/JESD36 (2.7 V to 3.6 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-B exceeds 200 V  
CDM ANSI/ESDA/Jedec JS-002 exceeds 1000 V  
Specified from -40 °C to +85 °C and -40 °C to +125 °C

[4] Valid for data inputs of bus hold parts only (74LVCH16245A). Note that control inputs do not have a bus hold circuit.  
[5] The specified sustaining current at the data input holds the input below the specified VI level.

[3] CPD is used to determine the dynamic power dissipation (PD in μW).  
PD = CPD × VCC 2 × fi × N + Σ(CL × VCC 2 × fo) where:  
fi = input frequency in MHz; fo = output frequency in MHz  
CL = output load capacitance in pF  
VCC = supply voltage in Volts  
N = number of inputs switching  
Σ(CL × VCC 2 × fo) = sum of the outputs.

Customers are responsible for the design and operation of their applications  
and products using Nexperia products, and Nexperia accepts no liability for  
any assistance with applications or customer product design. It is customer’s  
sole responsibility to determine whether the Nexperia product is suitable  
and fit for the customer’s applications and products planned, as well as

Nexperia does not accept any liability related to any default, damage, costs  
or problem which is based on any weakness or default in the customer’s  
applications or products, or the application or use by customer’s third party  
customer(s). Customer is responsible for doing all necessary testing for the

the internet at https://www.nexperia.com.  
Definitions  
Limiting values — Stress above one or more limiting values (as defined in  
the Absolute Maximum Ratings System of IEC 60134) will cause permanent  
damage to the device. Limiting values are stress ratings only and (proper)  
operation of the device at these or any other conditions above those  
given in the Recommended operating conditions section (if present) or the  
Characteristics sections of this document is not warranted. Constant or  
repeated exposure to limiting values will permanently and irreversibly affect  
the quality and reliability of the device.  
Draft — The document is a draft version only. The content is still under  
internal review and subject to formal approval, which may result in  
modifications or additions. Nexperia does not give any representations or  
warranties as to the accuracy or completeness of information included herein  
and shall have no liability for the consequences of use of such information.  
Short data sheet — A short data sheet is an extract from a full data sheet  
with the same product type number(s) and title. A short data sheet is  
intended for quick reference only and should not be relied upon to contain  
detailed and full information. For detailed and full information see the relevant  
full data sheet, which is available on request via the local Nexperia sales  
office. In case of any inconsistency or conflict with the short data sheet, the  
full data sheet shall prevail.

sold subject to the general terms and conditions of commercial sale, as  
published at http://www.nexperia.com/profile/terms, unless otherwise agreed  
in a valid written individual agreement. In case an individual agreement is  
concluded only the terms and conditions of the respective agreement shall  
apply. Nexperia hereby expressly objects to applying the customer’s general  
terms and conditions with regard to the purchase of Nexperia products by  
customer.  
Product specification — The information and data provided in a Product  
data sheet shall define the specification of the product as agreed between  
Nexperia and its customer, unless Nexperia and customer have explicitly  
agreed otherwise in writing. In no event however, shall an agreement be  
valid in which the Nexperia product is deemed to offer functions and qualities  
beyond those described in the Product data sheet.  
No offer to sell or license — Nothing in this document may be interpreted  
or construed as an offer to sell products that is open for acceptance or the  
grant, conveyance or implication of any license under any copyrights, patents  
or other industrial or intellectual property rights.

for the content in this document if provided by an information source outside  
of Nexperia.  
Non-automotive qualified products — Unless this data sheet expressly  
states that this specific Nexperia product is automotive qualified, the  
product is not suitable for automotive use. It is neither qualified nor tested in  
accordance with automotive testing or application requirements. Nexperia  
accepts no liability for inclusion and/or use of non-automotive qualified  
products in automotive equipment or applications.  
In no event shall Nexperia be liable for any indirect, incidental, punitive,  
special or consequential damages (including - without limitation - lost

or replacement of any products or rework charges) whether or not such  
damages are based on tort (including negligence), warranty, breach of  
contract or any other legal theory.  
In the event that customer uses the product for design-in and use in  
automotive applications to automotive specifications and standards,  
customer (a) shall use the product without Nexperia’s warranty of the  
product for such automotive applications, use and specifications, and (b)  
whenever customer uses the product for automotive applications beyond  
Nexperia’s specifications such use shall be solely at customer’s own risk,  
and (c) customer fully indemnifies Nexperia for any liability, damages or failed  
product claims resulting from customer design and use of the product for  
automotive applications beyond Nexperia’s standard warranty and Nexperia’s
