DS75491 MOS-to-LED Digit Driver/ Quad Segment Driver

The DS75491 and DS75492 are interface circuits designed to be used in conjunction with MOS integrated circuits and common-cathode LEDs in serially addressed multi-digit displays The number of drivers required for this time-multiplexed system is minimized as a result of the segment-address-and-digit-.
