LM393PT from STMicroelectronics, in a TSSOP-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 | Out1 | output | Open-collector output of comparator 1, with output sink current of 6 mA min and 18 mA typ at Vid = 1 V, Vo = 1.5 V and VOL of 80 mV typ at 4 mA. |
| 2 | In1- | input | Inverting input of comparator 1, with common-mode range 0 to (VCC+) - 1.5 V and not to go below -0.3 V. |
| 3 | In1+ | input | Non-inverting input of comparator 1, with common-mode range 0 to (VCC+) - 1.5 V and not to go below -0.3 V. |
| 4 | Vcc- | power_in | Negative supply, ground in single-supply operation; supply span (VCC+) - (VCC-) is 2 V to 36 V. |
| 5 | In2+ | input | Non-inverting input of comparator 2, with common-mode range 0 to (VCC+) - 1.5 V and not to go below -0.3 V. |
| 6 | In2- | input | Inverting input of comparator 2, with common-mode range 0 to (VCC+) - 1.5 V and not to go below -0.3 V. |
| 7 | Out2 | output | Open-collector output of comparator 2, with output sink current of 6 mA min and 18 mA typ at Vid = 1 V, Vo = 1.5 V and VOL of 80 mV typ at 4 mA. |
| 8 | Vcc+ | power_in | Positive supply, with supply span 2 V to 36 V (±1 V to ±18 V) and absolute maximum of 36 V. |
