GENERAL DESCRIPTION

The HI-8020 & HI-8120 high voltage display drivers are functional replacements for the AMI S5420 and Micrel MIC8013/8014 series. These CMOS products are designed to drive liquid crystal displays by converting 5 volt serial data to parallel segment and backplane waveforms with amplitudes up to 30 volts. The HI-8020 & HI-8120 differ from the HI-8010 by only the shift register clock and chip select gating logic. The HI-8020 has TTL logic inputs whereas the HI-8120 has CMOS logic inputs.

FEATURES

• 5 volt input translated to 30 volts or less

• Pin-out adaptable to drive 30, 32 or 38 LCD segments

• RC oscillator or high voltage (BP) clock input

• TTL compatible inputs (HI-8020 only)

• Low power consumption

• Industrial (-40°C to +85°C) & Military (-55°C to +125°C) temperature ranges

• Pin for pin compatible with the Micrel MIC8010/8011 series and the AMI S4520 series drivers

• Cascadable

• Military level processing available

• CMOS compatible inputs (HI-8120 only)

APPLICATIONS

• Dichroic Liquid Crystal Displays
