DM75491 MOS-to-LED quad segment driver

The OM75491 and OM75492 are interface circuits designed to be used in conjunction with MOS integrated circuits and common-cathode LED's in serially addressed multi-digit displays_ The number of drivers required for this time-multiplexed system is minimized as a result of the segmentaddress-and-digit.
