Exar Corporation XR-2271
The XR-2271 is a monolithic 7-digit or 7-segment display driver designed to interface MaS logic with fluorescent displays. It features active high logic and low input current. Each XR-2271 is capable of driving seven digits or segments of a display panel and provides complete input and output isolation.GENERAL DESCRIPTION
Since the output pull up resistors are incorporated on chip, no external parts are required to interface fluorescent displays. FUNCTIONAL BLOCK DIAGRAM INPUTSFEATURES
