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, HI-8150 and HI-8151  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 negative 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 blankingof thedisplayif the+5Vpower is lost.

The HI-8050, HI-8051, HI-8150 and HI-8151 are designed to replace t he HI-8010 and HI-8020 devices in all 5 volt applications. They offer significantly enhanced ESD protection along with a considerably faster serial input datarate.

The data of HI-8050, HI-8051, HI-8150 and HI-8151  is serially clocked into the device on the negative edge of the clock and latched in parallel to the segment outputs on the high to lowtransition of the load input. Serial output data changes on the positive edge of the clock allowingthecascadingofmultipledriversfor larger displays.

The HI-8050, HI-8051, HI-8150 and HI-8151  layout supports all previous pinouts of the HI-8010/HI-8020 products. In addition, newtechnology and features afford ne w packaging options. Consult your Holt Sales Representativetoexplorethepossibilities.
