LM393DT from STMicroelectronics, in a SO-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 | OUT1 | output | Open-collector output of comparator 1; VOL 80 mV typ at Isink = 4 mA, max sink current 18 mA at Vo = 1.5 V; output can be shorted to GND indefinitely but not to VCC+. |
| 2 | IN1- | input | Inverting input of comparator 1; common-mode range 0 V to VCC+ −1.5 V (0 V to VCC+ −2 V over full temperature range); input bias current 20 nA typ, offset current ±3 nA typ. |
| 3 | IN1+ | input | Non-inverting input of comparator 1; common-mode range 0 V to VCC+ −1.5 V; input may go up to +30 V without damage regardless of VCC+; input bias current 20 nA typ. |
| 4 | VCC- | power_in | Negative supply (ground reference); supports single supply 0 V (with VCC+ 2 V to 36 V) or split supply down to −18 V; input common-mode range includes this rail. |
| 5 | IN2+ | input | Non-inverting input of comparator 2; common-mode range 0 V to VCC+ −1.5 V; input may go up to +30 V without damage regardless of VCC+; input bias current 20 nA typ. |
| 6 | IN2- | input | Inverting input of comparator 2; common-mode range 0 V to VCC+ −1.5 V (0 V to VCC+ −2 V over full temperature range); input bias current 20 nA typ, offset current ±3 nA typ. |
| 7 | OUT2 | output | Open-collector output of comparator 2; VOL 80 mV typ at Isink = 4 mA, max sink current 18 mA at Vo = 1.5 V; output can be shorted to GND indefinitely but not to VCC+. |
| 8 | VCC+ | power_in | Positive supply; 2 V to 36 V single supply or ±1 V to ±18 V split supply; quiescent current 0.45 mA typ / 1 mA max at VCC = +5 V for both comparators. |
