**Gainsil** · Comparators · SOT-23-6

GS8706-TR from Gainsil, in a SOT-23-6. 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 | Push-pull comparator output, rail-to-rail and CMOS/TTL-compatible. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); VDD to VSS operates from 1.6V to 5.5V. |
| 3 | IN+ | input | Non-inverting comparator input, rail-to-rail with common-mode range of VSS-0.1V to VDD+0.1V. |
| 4 | IN- | input | Inverting comparator input, rail-to-rail with common-mode range of VSS-0.1V to VDD+0.1V. |
| 5 | REF | output | Integrated 1.2V voltage reference output (1190mV min to 1238mV max, 4mA reference output current). |
| 6 | VDD | power_in | Positive supply, 1.6V to 5.5V (absolute maximum 7.5V); place a 0.1uF ceramic capacitor close to this pin. |
