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 displays The number of drivers required for this time-multiplexed system is minimized as a result of the segment-address-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
