GENERAL DESCRIPTION
The HI-8050, HI-8051, HI-8150 and HI-8151 are CMOS integrated circuits designed for high voltage LCD display drive applications. The HI-8050 & HI-8051 have TTL logic inputs whereas the HI-8150 & HI-8151 have CMOS logic inputs. They drive up to 38 segments at voltages between +5 and -30 volts. The optional voltage converter on the HI-8050 & HI-8150 can be used to generate the negative display drive voltage. All products have test inputs to facilitate opens and shorts testing as well as automatic blanking of the display if the +5V power is lost.
