LM293N

HGSEMI · Comparators · DIP-8

LM293N from HGSEMI, in a DIP-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 output Channel 1 open-drain output, with typical VOL of 0.1V at IOL=4mA.
2 1IN- input Channel 1 inverting (negative) input, common-mode range 0 to VCC-1.5V.
3 1IN+ input Channel 1 non-inverting (positive) input, common-mode range 0 to VCC-1.5V.
4 VEE power_in Negative supply, connected to GND in single-supply operation (dual supply down to -16V).
5 2IN+ input Channel 2 non-inverting (positive) input, common-mode range 0 to VCC-1.5V.
6 2IN- input Channel 2 inverting (negative) input, common-mode range 0 to VCC-1.5V.
7 2OUT output Channel 2 open-drain output, with typical VOL of 0.1V at IOL=4mA.
8 VCC power_in Positive supply, 2V to 32V single supply (absolute maximum 36V).
