GENERAL DESCRIPTION

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.

FEATURES

• 4 MHz serial input data rate

• 85 segment outputs

• Cascadable

• 5 Volt inputs translated to 35 Volts

• Test pins allow hardware all ON, all OFF or alternating

• Monitors backplane oscillation and forces all segments to OFF condition if below 10Hz

• Negative voltage converter available on-chip

• CMOS low power

• Military processing available

APPLICATIONS

• Dichroic Liquid Crystal Displays

• Standard Liquid Crystal Displays
