HV5812 20-Channel Serial-Input Vacuum Fluorescent Display Driver for Anode or Grid Features General Description HVCMOS Technology for High Performance The HV5812 is a 20-channel serial-input vacuum fluorescent display driver. It combines a 20-bit CMOS Operating Voltage of up to 80V shift register, data latches and control circuitry with High-speed Source Driver high-voltage MOSFET outputs. The HV5812 is 5V CMOS Logic Circuitry primarily designed for vacuum fluorescent displays. Up to 5 MHz Data Input Rate The CMOS shift register and latches allow direct Excellent Noise Immunity interfacing with microprocessor-based systems. Data Flexible High-voltage Supplies input rates are typically over 5 MHz with 5V logic supply. Especially useful for interdigit blanking, the Applications blanking input disables the output source drives and turns on the sink drivers. Using with TTL may require Display Driver external pull-up resistors to ensure an input logic high.
