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.

Absolute Maximum Ratings are those values beyond 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. All voltages are referenced to GND.

Power-up sequence should be the following:
1. Connect ground.
2. Apply VDD.
3. Set all inputs (Data, CLK, etc.) to a known state.
4. Apply VPP.
The VPP should not drop below VDD during operation.
Power-down sequence should be the reverse of the above.
