GS8740-TR from Gainsil, in a SOT-23-5. 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 | OUT | output | Comparator output, rail-to-rail and CMOS/TTL-compatible. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); supply range VDD to VSS is 2.7V to 5.5V, absolute maximum 7.5V. |
| 3 | IN+ | input | Non-inverting comparator input, rail-to-rail with common-mode range VSS-0.1V to VDD+0.1V. |
| 4 | IN- | input | Inverting comparator input, rail-to-rail with common-mode range VSS-0.1V to VDD+0.1V. |
| 5 | VDD | power_in | Positive supply, 2.7V to 5.5V, with a 0.1uF ceramic bypass capacitor placed close to the pin. |
