High-Voltage 7-Digit Display Driver
FUNCTIONAL BLOCK DIAGRAM
The XR-2272 is a monolithic high voltage display driver
array specifically designed to drive gas-filled digit dis-
plays. The circuit is made up of seven independent digit
driver sections in the same monolithic package. Its
main application is to act as buffer interface between
MOS outputs and the anodes of a gas discharge panel.
The XR-2272 is particularly well suited to interfacing
with Panaplex II type displays.

The XR-2272 high voltage display driver features seven
independent sections, each capable of switching - 75
V at up to 20 mA. Each has active low inputs and mono-
lithic pull-up resistors. The output is an emitter follower.
