LM311D Description

Short technical summary and product information.

The LM311D from STMicroelectronics is a versatile, high-speed voltage comparator designed for general-purpose applications. This single-channel comparator offers a wide operating supply voltage range, from 3.5V to 30V, making it suitable for various circuit designs.

 

Key electrical characteristics include a fast propagation delay time of 0.115µs and an open-collector output type, compatible with DTL, MOS, RTL, and TTL logic families. It also features strobe and Vos adjustment pins for enhanced control.

 

The device is available in an 8-SOIC surface-mount package, with an operating temperature range of 0°C to 70°C. Its design allows for isolation of inputs and outputs from system ground, and the outputs can drive loads referenced to ground, VCC+, or VCC-. The LM311D is capable of switching voltages up to 50V at 50mA.

 

This comparator is well-suited for applications requiring fast response times and flexible output configurations. Its robust design and wide operating parameters make it a reliable choice for demanding electronic systems.
