1A229

PRODUCT INFORMATION 870 nm 1A229 High-Performance LED Battery-Operated Equipment This device operates at very low drive current, which makes it well suited for battery-operated equipment. In fact, it can be driven directly by TTL circuitry. Optical and Electrical Characteristics PARAMETER SYMBOL MIN. TYP . MAX.
