Notes:

1. Device will survive (but operation may not be specified or guaranteed) at

these extremes.

3. Duty cycle is limited by the total power dissipated in the package.

4. For operation above 25°C ambient derate linearly to 85°C at 20mW/°C.

General Description

The HV65 is a low-voltage serial to high-voltage parallel converter

with push-pull outputs. This device has been designed for use as

a driver circuit for LCD displays. It can also be used in any

application requiring multiple output high-voltage current sourc-

ing and sinking capabilities. The inputs are fully CMOS compat-

ible.

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

control logic to perform the polarity select of the outputs. HVout1

is connected to the first stage of the shift register through the

polarity logic. Data is shifted through the shift register on the logic

low to high transition of the clock. A DIR pin causes data shifting

counterclockwise when grounded and clockwise when connected

to V

This output reflects the current status of the last bit of the shift

register. Operation of the shift register is not affected by the LE

(latch enable) or the POL (polarity) inputs. 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 after LE transition from

high to low.
