# GSV331R-CR

**Gainsil** · Comparators · SC-70-5

GSV331R-CR from Gainsil, in a SC-70-5. 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 -0.1 V to +5.6 V at VS = 5.5 V, and absolute maximum of Vss-0.5 V to VDD+0.5 V. |
| 2 | VSS | power_in | Negative supply or ground pin, with VDD to VSS supply voltage of 1.8 V to 5.5 V operating and -0.5 V to +7.5 V absolute maximum. |
| 3 | IN- | input | Inverting comparator input with rail-to-rail common-mode range of -0.1 V to +5.6 V at VS = 5.5 V, and absolute maximum of Vss-0.5 V to VDD+0.5 V. |
| 4 | OUT | output | Open-drain, rail-to-rail, CMOS/TTL-compatible comparator output with 70 ns typical propagation delay. |
| 5 | VDD | power_in | Positive supply pin for 1.8 V to 5.5 V single-supply operation (absolute maximum 7.5 V), with a 0.1 uF ceramic bypass capacitor recommended close to the pin. |
