Description
MC75492 MOS-to-LED Hex Digit Driver
Description
The MC75491 and MC75492 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
50 mA source or sink capability per driver (MC75491)
250 mA sink capability per driver (MC75492)
MOS compatibility (low input current)Y Low standby power
High-gain Darlington circuits
