CMOS HIGH VOLTAGE DISPLAY DRIVER

August 2005

GENERALDESCRIPTION

APPLICATIONS

! Dichroic Liquid Crystal Displays

The HI-8040 is a CMOS integrated circuit designed for high

voltage LCD display drive applications. It can drive 85

segments at voltages between +5 and -30 volts. An optional

voltage converter can generate the negative display drive

voltage. Test inputs facilitate opens and shorts testing. The

backplane frequency is checked and, as long as power is

available, the segments are shut "Off" if the frequency

becomes too low.

! Standard Liquid Crystal Displays

! MEMS Drivers

PIN CONFIGURATION (Top View)

The HI-8040 is part of a family of display drivers which

control segment information in the same way. Data is

serially clocked into the device and the data for all segment

outputs are latched in parallel when the Load input

transitions from high to low. With the Data Out from the shift

segment outputs. The shift register is 85 bits long.
