The HI-8051PQT is a CMOS integrated circuit designed for high voltage LCD display drive applications. This device has TTL logic inputs. The HI-8051PQT drives up to 38 segments at voltages between +5 and -30 volts. All HI-8051 Series 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 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 displays.
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. In addition, new technology and features afford new packaging options.
