LM393BIDSGR

Texas Instruments · Comparators · WSON-8-EP(2x2)

LM393BIDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 1OUT tri_state Output of comparator 1 with open-drain configuration; maximum sink current 25 mA absolute maximum for B-version.
2 1IN- input Inverting input of comparator 1; input common-mode voltage range (V-) to (V+) - 1.5 V at 25°C.
3 1IN+ input Non-inverting input of comparator 1; input common-mode voltage range (V-) to (V+) - 1.5 V at 25°C.
4 GND power_in Ground reference pin and connection point for exposed thermal pad on package underside.
5 2IN+ input Non-inverting input of comparator 2; input common-mode voltage range (V-) to (V+) - 1.5 V at 25°C.
6 2IN- input Inverting input of comparator 2; input common-mode voltage range (V-) to (V+) - 1.5 V at 25°C.
7 2OUT tri_state Output of comparator 2 with open-drain configuration; maximum sink current 25 mA absolute maximum for B-version.
8 VCC power_in Positive power supply pin; recommended operating voltage 2 V to 36 V for LM393B.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
