LM311P – High-Speed Voltage Comparator

MPN:LM311P

The LM311P is a high-speed, precision voltage comparator from Texas Instruments, designed to compare two analog input voltages and provide a digital-compatible output. It features an open-collector output, allowing it to interface easily with TTL, CMOS, and other logic families using an external pull-up resistor.

The LM311P operates over a wide supply voltage range and offers fast response time, low input offset voltage, and high reliability. Housed in a DIP package, it is especially suitable for through-hole designs, prototyping, educational projects, and industrial control systems. Common applications include zero-crossing detectors, level detectors, pulse generators, and PWM circuits.
