Overview
The LM211PWR, produced by Texas Instruments, is a single high-speed voltage comparator. It is part of the LM111, LM211, and LM311 family of devices, 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 LM211 is capable of driving loads referenced to ground, VCC+, or VCC-, and its output levels are compatible with most TTL and MOS circuits. This comparator can drive lamps or relays and switch voltages up to 50 V at currents up to 50 mA. The device also features offset balancing and strobe capabilities, with the outputs able to be wire-OR connected.
