Texas Instruments LM211

the lm111 lm211 and lm311 are single high-speed voltage comparators. these devices are designed to operate from a wide range of power-supply voltages including 15-v supplies for operational amplifiers and 5-v supplies for logic systems. the output levels are compatible with most ttl and mos circuits. these comparators are capable of driving lamps or relays and switching voltages up to 50 v at 50 ma. all inputs and outputs can be isolated from system ground. the outputs can drive loads referenced to ground vcc+ or vcc. offset balancing and strobe capabilities are available and the outputs can be wire-or connected. if the strobe is low the output is in the off state regardless of the differential input.
