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.
