The STV7697A is a scan driver for Plasma
Display Panel (PDP) implemented inST’s
proprietary BCD technology. Using a 64-bit
cascadable 20 MHz shift register, it drives 64 high
current & high voltage outputs. By serially
connecting several STV7697A, any vertical pixel
definition can be performed. The STV7697A is
supplied with a separated 160V power output
supply and a 5V logic supply.All command inputs
are CMOS compatible.
The STV769 7A package is a 100 pins PQFP.

The STV7697Acontains all the logic and the power circuits necessary to drive rows of a Plasma
Display Panel (P. D. P.). The state of the displayed
line is loaded into the shift register. Data are shifted at each low to high transition of the (CLK) shift
clock. After 64 shifts the first bit is available at the
serial output. This output can be used to cascade
several drivers to perform any vertical resolution.
The forward / reverse (F/R) input is used to select
the direction of the shift register, data input/output
status is set according to the selected direction.
SIN, CLK, STB inputs
are Smith trigger inputs . If not used on the application, F/R, BLK, POL logical inputs are internaly
pulled to level ”1”. The maximum frequency of the
shift clock is 20 MHz.
All the data are memorized into the latch stage
when the strobe input (STB) is pulled high.
Blanking input (BLK) forces the power outputs to
high level when pulled high with polarity input
(POL) at high level and forced to low level with
POL at low level.
The level of the power output is inverted when the
polarity command (POL) is pulled high.
Sustain currentmust not be sunk in the power outputtoVPPwhen the power supply is applied.
