HI-8020 Series

September 1999

PIN CONFIGURATION (Top View)

GENERAL DESCRIPTION

The HI-8020 high voltage display driver is a

functional replacement for the AMI S5420 and

Micrel MIC8013/8014 series. This CMOS product

is 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 differs from the HI-8010 by

only the shift register clock logic gating with chip

select.

The chip can drive up to 38 segments and has 4

possible shift register data taps to provide options

to cascade devices for larger displays. Data is

clocked into a 38 stage shift register and parallel

latched b efore the output translators by a Load

input.
