CMOS HIGH VOLTAGE DISPLAY DRIVER

GENERAL DESCRIPTION

APPLICATIONS

! Dichroic Liquid Crystal Displays

! Standard Liquid Crystal Displays

! 5 Volt Serial Data to Parallel High Voltage

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 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

blanking of the display if the +5V power is lost.

The HI-8050 and HI-8150 are designed to replace the

HI-8010 and HI-8020 devices in all 5 volt applications. They

offer significantly enhanced ESD protection along with a

considerably faster serial input data rate.

The data 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 low transition of the load input. Serial

output data changes on the positive edge of the clock

allowing the cascading ofmultiple drivers for larger displays.

The device layout supports all previous pinouts of the

HI-8010/HI-8020 products. In addition, new technology and

features afford ne w packaging options. Consult your Holt

Sales Representative to explore the possibilities.
