75491 Datasheet (National Semiconductor) - MOS-to-LED Quad Segment Driver

75491, MOS-to-LED 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-
