DS75491 Datasheet, PDF (1/4 Pages) National Semiconductor (TI) – MOS-to-LED Digit Driver, Quad Segment Driver

February 1995
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
Features
Y _{50 mA source or sink capability per driver (DS75491)}
Y _{250 mA sink capability per driver (DS75492)}
Y _{MOS compatability (low input current)}
Y _{Low standby power}
Y _{High-gain Darlington circuits}
