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 | 1OUT | output | Output of op-amp channel 1. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). Output swings within tens of mV of both supply rails under light load. |+| 2 | 1IN- | input | Inverting input of op-amp channel 1. High-impedance CMOS input, typical bias current 1 pA. Input voltage must remain within VDD- - 0.3 V to VDD+. |+| 3 | 1IN+ | input | Non-inverting input of op-amp channel 1. High-impedance CMOS input, typical bias current 1 pA. Common-mode range includes the negative rail (VDD-). |+| 4 | VDD+ | power_in | Positive (highest) supply pin. Single-supply operation up to +8 V absolute max; typical characterization at ±2.5 V split or +5 V single supply. Bypass locally with 0.1 µF to VDD-. |+| 5 | 2IN+ | input | Non-inverting input of op-amp channel 2. High-impedance CMOS input, typical bias current 1 pA. Common-mode range includes the negative rail. |+| 6 | 2IN- | input | Inverting input of op-amp channel 2. High-impedance CMOS input, typical bias current 1 pA. |+| 7 | 2OUT | output | Output of op-amp channel 2. Rail-to-rail output stage; ±50 mA absolute max output current. |+| 8 | 3OUT | output | Output of op-amp channel 3. Rail-to-rail output stage; ±50 mA absolute max output current. |+| 9 | 3IN- | input | Inverting input of op-amp channel 3. High-impedance CMOS input, typical bias current 1 pA. |+| 10 | 3IN+ | input | Non-inverting input of op-amp channel 3. High-impedance CMOS input, typical bias current 1 pA. |+| 11 | VDD- | power_in | Negative (lowest) supply pin. Tie to GND for single-supply operation, or to the negative rail for split-supply operation. Absolute max -8 V relative to the supply midpoint. |+| 12 | 4IN+ | input | Non-inverting input of op-amp channel 4. High-impedance CMOS input, typical bias current 1 pA. |+| 13 | 4IN- | input | Inverting input of op-amp channel 4. High-impedance CMOS input, typical bias current 1 pA. |+| 14 | 4OUT | output | Output of op-amp channel 4. Rail-to-rail output stage; ±50 mA absolute max output current. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOP-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `TLC2274CDRCDR`+- `TLC2274CDRIDR`+- `TLC2274CDRCD`+- `TLC2274CDRID`++## CAD (KiCad official)++- Symbol: `TLC2274CDR`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/tlc2274cdr-datasheet.pdf) (30 pp, sha256 `ead5615846e4c74e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
