DS8870 Hex LED Digit Driver
General Description
The DS8870 is an interface circuit 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 segment-address-and-digitscan method of LED drive
Features
Y Sink capability per driver 350 mA Y MOS compatibility (low input current) Y Low standby power Y High-gain Darlington circuits
