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). |
