General Description
The DS75491and DS75492are interface circuits designedbe usedin conjunction with MOS integrated circuitsand
common-cathode LEDsin serially addressed multi-digitdis-
plays. The numberof drivers requiredfor this time-multi-
plexed systemis minimizedasa resultofthe segment-ad-
dress-and-digit-scan methodof LED drive.
Features50mA sourceor sink capabilityper driver (DS75491) 250mA sink capabilityper driver (DS75492) MOS compatability (low input current) Low standby power High-gain Darlington circuits
