~ DM75491 MOS-to-LED quad segment driver
C DM75492 MOS-to-LED h~x digit driver
general description
The OM75491 and OM75492 are interface circuits designed to be used in conjunction with MOS integrated circuits and common-cathode LED's in serially addressed multi-digit displays_ The number of drivers required for this time-multiplexed system is minimized as a result of the segmentaddress-and-digit-scan method of LED drive_
features
• Source or sink capability per driver (DM75491)
50 mA
• Sink capability per driver (DM75492)
250 mA
• MOS compatability (low input current) • Low standby power, • High-gain Darlington circuits
