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.
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 of multiple drivers for larger dis-
plays.
The device layout supports all previous pinouts of the
HI-8010/HI-8020 products.
and features afford new packaging options. Consult your
Holt Sales Representative to explore the possibilities.
