HV5812

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