The HI-8020 / HI-8120 Series 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.

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 a variety of ceramic and plastic packaging including DIP; leaded and leadless chip carriers; and J-lead and gull-wing quad flat packs.
