LM393BIDGKR

Texas Instruments · Comparators · VSSOP-8

LM393BIDGKR from Texas Instruments, in a VSSOP-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 1OUT tri_state Comparator 1 open-drain output that pulls low up to 25 mA when 1IN- exceeds 1IN+.
2 1IN- input Comparator 1 negative input with ±38V differential input rating and common-mode range from ground to VCC-2.0V.
3 1IN+ input Comparator 1 positive input with ±38V differential input rating and common-mode range from ground to VCC-2.0V.
4 GND power_in Ground reference and connection to negative supply.
5 2IN+ input Comparator 2 positive input with ±38V differential input rating and common-mode range from ground to VCC-2.0V.
6 2IN- input Comparator 2 negative input with ±38V differential input rating and common-mode range from ground to VCC-2.0V.
7 2OUT tri_state Comparator 2 open-drain output that pulls low up to 25 mA when 2IN- exceeds 2IN+.
8 VCC power_in Positive power supply rated for 2 to 36V operating range.
