LM393BIDDFR

Texas Instruments · Comparators · TSOT-23-8

LM393BIDDFR from Texas Instruments, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Open-drain output of Comparator 1; sinks maximum 21 mA at VOL = 1.5V with input overdrive VID = −1V.
2 1IN- input Inverting input of Comparator 1; common-mode voltage range (V−) to (V+)−2.0V over temperature; input bias current maximum −25 nA.
3 1IN+ input Non-inverting input of Comparator 1; common-mode voltage range (V−) to (V+)−2.0V over temperature; input bias current maximum −25 nA.
4 GND power_in Ground connection; reference potential for the circuit.
5 2IN+ input Non-inverting input of Comparator 2; common-mode voltage range (V−) to (V+)−2.0V over temperature; input bias current maximum −25 nA.
6 2IN- input Inverting input of Comparator 2; common-mode voltage range (V−) to (V+)−2.0V over temperature; input bias current maximum −25 nA.
7 2OUT output Open-drain output of Comparator 2; sinks maximum 21 mA at VOL = 1.5V with input overdrive VID = −1V.
8 VCC power_in Positive power supply; operating range 2V to 36V with typical quiescent current 400-600 µA at 5V.
