Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN(+) | input | Non-inverting comparator input. Input common-mode range includes ground and extends up to VCC-1.5V; may go to +30V without damage. Input bias current is typ. 25 nA (out of the pin due to PNP input stage). |+| 2 | GND | power_in | Device ground / negative supply reference. In single-supply operation, tie to 0V; in dual-supply operation, tie to the negative rail (down to -18V). |+| 3 | IN(-) | input | Inverting comparator input. Same common-mode constraints as IN(+); differential input voltage range equals the supply voltage (up to ±36V). |+| 4 | Output | output | Open-collector comparator output. Requires an external pull-up resistor to VCC (or another logic rail up to +36V). Low-level output voltage is typ. 250 mV at IOUT=4 mA; sink capability is typ. 16 mA. Compatible with TTL, DTL, ECL and CMOS. |+| 5 | VCC | power_in | Positive supply pin. Single-supply range +2V to +36V, or ±1V to ±18V split supply. Supply current is typ. 0.2 mA at VCC=5V and independent of supply voltage. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | SOT-25-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `TS391AG-AF5-R`+- `TS391AG-AF5-RTS391AG-AL5-R`++## CAD (KiCad official)++- Symbol: `TS391AG-AF5-R`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-25-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UTC Unisonic Tech datasheet](docs/ts391ag-af5-r-datasheet.pdf) (6 pp, sha256 `148a7cf2cdeb20cf`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
