HI-8050PQI

The HI-8050 and HI-8150   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. 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 theHI-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 of HI-8050 and HI-8150  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 displays.

The HI-8050 and HI-8150  layout supports all previous pinouts of the HI-8010/HI-8020 products. In addition, new technology and features afford new packaging options. Consult your Holt Sales Representative to explore the possibilities.
