General Description
The Supertex 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 vac-
uum-fluorescent displays.
The CMOS shift register and latches allow direct interfacing
with microprocessor based systems. Data input rates are typi-
cally over 5.0MHz with 5.0V logic supply. Especially useful for
interdigit blanking, the BLANKING input disables the output
source drives and turns on the sink drivers. Use with TTL may
require external pull-up resistors to ensure an input logic high.
