GS8749-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 | IN+ | input | Non-inverting comparator input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V (absolute maximum VSS-0.5V to VDD+0.5V). |
| 2 | VSS | power_in | Negative supply pin, ground in single-supply operation. |
| 3 | IN- | input | Inverting comparator input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V (absolute maximum VSS-0.5V to VDD+0.5V). |
| 4 | OUT | output | Open-drain, CMOS/TTL-compatible comparator output that requires an external pull-up resistor (RUP). |
| 5 | VDD | power_in | Positive supply pin, 2.7V to 5.5V operation (7.5V absolute maximum), with a 0.1uF ceramic bypass capacitor placed close to it. |
