HI-8040QT

The HI-8040 is a CMOS integrated circuit designed for high voltage LCD display drive applications. It can drive 85 segments at voltages between +5 and -30 volts. An optional negative converter can generate the negative display drive voltage. Test inputs facilitate opens and shorts testing. The backplane frequency is checked and, as long as power is available, the segments are shut “OFF” if the frequency becomes too low.
