CMOS HIGH VOLTAGE DISPLAY DRIVER
GENERALDESCRIPTION
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
blankingof thedisplayifthe+5Vpowerislost.
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
considerablyfasterserialinputdatarate.
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
allowingthecascadingofmultipledriversforlargerdisplays.
The device layout supports all previous pinouts of the
HI-8010/HI-8020 products. Inaddition, newtechnologyand
features afford new packaging options. Consult your Holt
