General Description

The HV9708 is a low voltage serial to high voltage parallel

converters with push-pull outputs. This device has been designed

for use as a driver for AC-electroluminescent displays.It can also

be used in any application requiring multiple output, high voltage

current sourcing and sinking capabilities such as driving plasma

panels, vacuum ﬂuorescent, or large matrix LCD displays. The

inputs are fully CMOS compatible.

This device consists of a 32-bit shift register, 32 latches, and

control logic to perform the polarity select and blanking of the

outputs. HV

through the polarity and blanking logic. Data is shifted through

the shift register on the logic low to high transition of the clock.

The HV9708 shifts data in the clockwise direction when viewed

from the top of the package. A data output buffer is provided

for cascading devices.This output reﬂects the current status of

the last bit of the shift register (HV

the POL (polarity) in-puts. Transfer of data from the shift register

to the latch occurs when the LE (latch enable) input is high. The

data in the latch is stored when LE is low.
