General Description
The MM74C911 DISPLAY controller is an interface element with memory that drives a 4-digit, 8-SEGMENT LED DISPLAY. The MM74C911 allows individual control of any SEGMENT in the 4-digit DISPLAY. The number of SEGMENTs per digit can be expanded without any external components. For example, two MM74C911’s can be cascaded to drive a 16-SEGMENT alpha-numeric DISPLAY

Features
■ Direct SEGMENT drive (100 mA typ.) 3-STATE
■ 4 registers addressed like RAM
■ Internal oscillator and scanning circuit
■ Direct base drive to digit transistor
■ SEGMENT expandability without external components
■ TTL compatible inputs
■ Power saver mode—5 µW (typ.)
