1 / 7 page  HI-8020/HI-8120 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. ! ! ! Dichroic Liquid Crystal Displays Standard Liquid Crystal Displays Vacuum Fluorescent Displays !
