General Description
The Supertex HV5812 is a 20-channel serial input vacuum
fluorescent display driver. It combines a 20-bit CMOS shift regis-
ter, data latches, and control circuitry with high voltage MOSFET
outputs. The HV5812 is primarily designed for vacuum-fluores-
cent displays.
The CMOS shift register and latches allow direct interfacing with
microprocessor-based systems. Data input rates are typically
over 5.0MHz with 5V logic supply. Especially useful for inter-digit
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.

Notes:
1. All voltages are referenced to ground. Absolute maximum ratings
are those values at which damage to the device may occur.
Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may
affect device reliability.
