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 prod-
ucts 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.
Both devices can drive up to 38 segments and have 3
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
before the output translators by a Load input.
The HI-8020 & HI-8120 are available in ceramic
leadless chip carriers and plastic PLCC packages.
