Overview
The LM311PWG4 is a high-speed voltage comparator from Texas Instruments, part of the LMx11 series. This device is designed to operate over a wide range of power supply voltages, including single 5-V supplies and standard ±15-V supplies. It is compatible with most TTL and MOS circuits and can drive loads such as lamps or relays, switching voltages up to 50 V at currents as high as 50 mA. The LM311PWG4 is housed in an 8-pin TSSOP package and is specified for operation over a temperature range of 0°C to 70°C.
