Product Summary

The NTE75491B is a monolithic 4-segment MOS-to-LED anode driver in a 14-lead plastic DIP-type package designed to be used together with MOS integrated circuits and common cathode LEDs in serially addressed multidigit displays. This time multiplexed system, which uses a segment address and digital scan method of LED drive, minimizes the number of drivers required.
