General Description
The HV6810 is a monolithic integrated circuit designed
to drive a dot matrix or segmented vacuum fluorescent
display (VFD). These devices feature a serial data output to
cascade additional devices for large displays.
A 10-bit data word is serially loaded into the shift register
on the positive-going transition of the clock. Parallel data
is transferred to the output buffers through a 10-bit D-type
latch while the latch enable input is high, and is latched
when the latch enable is low. When the blanking input is
high, all of the outputs are low.
Outputs are structures formed by double-diffused MOS
(DMOS) transistors with output voltage ratings of 80V and
25mA source-current capability. All inputs are compatible
with CMOS levels.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated
in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device
reliability. All voltages are referenced to GND.
