TI LM211DR High-Speed Differential Comparator SOIC-8

The Texas Instruments LM211DR is a single high-speed differential voltage comparator featuring strobe capability and separate collector and emitter output connections. It can operate from a single 5V supply, while TI specifies a recommended total supply range of 3.5V to 30V, making it suitable for voltage detection, oscillators, peak detectors, industrial control, and general comparator applications.

Under the specified ±15V, 25°C switching test conditions, the LM211 provides a typical 115ns low-to-high response time and 165ns high-to-low response time. Typical input offset voltage is 0.7mV, with a maximum of 3mV at 25°C and 4mV over the full LM211 temperature range.

Typical input bias current is 75nA, with 100nA maximum at 25°C and 150nA maximum over temperature. The device uses an open-collector NPN output stage with an isolated emitter, allowing loads to be referenced independently and supporting switching of up to 50V at 50mA. Strobe, offset balance, and wire-OR operation are also supported.

The exact LM211DR orderable device comes in an 8-pin SOIC (D) package measuring approximately 4.90 × 3.91mm and operates from -40°C to +85°C. The R suffix denotes a 2,500-piece large tape-and-reel package. TI currently lists the part as Active, RoHS and REACH compliant, with MSL Level 1 classification.
