DS75491 MOS-to-LED Quad Segment Driver
DS75492 MOS-to-LED Hex Digit Driver
General Description
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 dis-
plays The number of drivers required for this time-multi-
plexed system is minimized as a result of the segment-ad-
dress-and-digit-scan method of LED drive
