C DM75492 MOS-to-LED h~x digit driver general description
The OM75491 and OM75492 are interface circuits designed to be used in conjunction with MOS integrated circuits and mon-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-scan method of LED drive_
