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 high.
