DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD16520,16520A
VERTICAL DRIVER FOR CCD SENSORS
DESCRIPTION
The µ PD16520 and µ PD16520A are vertical drivers for CCD image sensors that have a level conversion circuit and
a 3-level output function. Since it incorporates a CCD vertical register driver equivalent to the µ PD16510 (10
channels, consisting of six 3-level channels and four 2-level channels) and a VOD shutter driver (1 channel), it is ideal
as a vertical driver for multiple-electrode high-pixel CCD transfer type area image sensors employed in digital still
cameras.
The µ PD16520 and µ PD16520A use a CMOS process to achieve optimum transmission delay characteristics for
vertical driving of CCD image sensors, as well as output on-state resistance characteristics. The µ PD16520 and
µ PD16520A also support low-voltage logic (logic power supply voltage: 2.0 to 5.5 V).
FEATURES
• CCD vertical register driver: 10 channels (3-level: 6 channels, 2-level: 4 channels)
• VOD shutter driver: 1 channel
• High withstanding voltage: 33 V MAX.
• Low-output on-state resistance: 30 Ω TYP.
• Low-voltage input supported (Logic power supply voltage: 2.0 to 5.5 V)
• Latch-up free
• Same drive capacity as µ PD16510
• Small package: 38-pin plastic SSOP (7.62 mm (300) )
• Super small package: 42-pin wafer level CSP
APPLICATIONS
Digital still cameras, digital video cameras, etc.

6. NOTE ON USE
6.1 Power ON/OFF Sequence
In the µ PD16520 and µ PD16520A, a PN junction (diode) exists between VDD2 → VDD1, input pin (TI1 to TI6, PG1
to PG6, BI1 to BI4, and SUBI) → VCC, so that in the case of voltage conditions: VDD2 > VDD1, input pin voltage (TI1
to TI6, PG1 to PG6, BI1 to BI4, and SUBI) > VCC, an abnormal current flows. Therefore, when turning the power
ON/OFF, make sure that the following voltage conditions are satisfied: VDD2 ≤ VDD1, input pin voltage (TI1 to TI6,
PG1 to PG6, BI1 to BI4, and SUBI) ≤ VCC. Also, to minimize the negative potential applied to the SUB pin of the CCD
image sensor, following the power ON/OFF sequence described below.
(1) Power ON
<1> Powering ON VCC
Make sure that input pin voltage (TI1 to TI6, PG1 to PG6, BI1 to BI4, and SUBI) ≤ VCC. Also, when Vsb = 2 V,
make sure that VCC reaches the rated voltage.
<2> Powering ON Vsb, VDD1, VDD2a, VDD2b and VSS
At this time, make SUBI high level (0.8VCC or higher) .

NOTES FOR CMOS DEVICES
VOLTAGE APPLICATION WAVEFORM AT INPUT PIN
1
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the
CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may
malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed,
and also in the transition period when the input level passes through the area between VIL (MAX) and
V
IH (MIN).
HANDLING OF UNUSED INPUT PINS
2
Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is
possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND
via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must
be judged separately for each device and according to related specifications governing the device.
3
PRECAUTION AGAINST ESD
A strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as
much as possible, and quickly dissipate it when it has occurred. Environmental control must be
adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that
easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static
container, static shielding bag or conductive material. All test and measurement tools including work
benches and floors should be grounded. The operator should be grounded using a wrist strap.
Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for
PW boards with mounted semiconductor devices.
4
STATUS BEFORE INITIALIZATION
Power-on does not necessarily define the initial status of a MOS device. Immediately after the power
source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does
not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the
reset signal is received. A reset operation must be executed immediately after power-on for devices
with reset functions.
5
POWER ON/OFF SEQUENCE
In the case of a device that uses different power supplies for the internal operation and external
interface, as a rule, switch on the external power supply after switching on the internal power supply.
When switching the power supply off, as a rule, switch off the external power supply and then the
internal power supply. Use of the reverse power on/off sequences may result in the application of an
overvoltage to the internal elements of the device, causing malfunction and degradation of internal
elements due to the passage of an abnormal current.
The correct power on/off sequence must be judged separately for each device and according to related
specifications governing the device.
6
INPUT OF SIGNAL DURING POWER OFF STATE
Do not input signals or an I/O pull-up power supply while the device is not powered. The current
injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and
the abnormal current that passes in the device at this time may cause degradation of internal elements.
Input of signals during the power off state must be judged separately for each device and according to
related specifications governing the device.
