LM311PWR

Texas Instruments · Comparators · TSSOP-8

LM311PWR from Texas Instruments, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EMIT OUT output Output emitter capable of driving loads referenced to ground or supply rails, rated for maximum 30V from emitter to VCC-.
2 IN+ input Noninverting input of the differential comparator accepting input voltages between VCC- + 0.5V and VCC+ - 1.5V.
3 IN- input Inverting input of the differential comparator accepting input voltages between VCC- + 0.5V and VCC+ - 1.5V.
4 VCC- power_in Negative supply voltage rail with minimum rating of -18V.
5 BALANCE input Offset voltage balance adjustment input.
6 BAL/STRB input Strobe input that drives the output to the off state when pulled low.
7 COL OUT output Output collector capable of driving loads referenced to ground or supply rails, rated for maximum 40V from collector to VCC-.
8 VCC+ power_in Positive supply voltage rail with maximum rating of +18V.
