**STMicroelectronics** · Operational Amplifier · TSSOP-14

TS974IYPT from STMicroelectronics, in a TSSOP-14. 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 | OUT1 | output | Output of op-amp channel 1. Rail-to-rail voltage swing (VOH ≥ 2 V, VOL ≤ -2 V at VCC = ±2.5 V, RL = 2 kΩ). Typical short-circuit source current 1.5 mA / sink 100 mA. |
| 2 | IN1- | input | Inverting input of op-amp channel 1. Input bias current typ. 200 nA; common-mode range VDD+1.15 V to VCC-1.15 V. |
| 3 | IN1+ | input | Non-inverting input of op-amp channel 1. Input bias current typ. 200 nA; common-mode range VDD+1.15 V to VCC-1.15 V. |
| 4 | VCC+ | power_in | Positive supply rail. Operating range 2.7 V to 10 V single-supply, or ±1.35 V to ±5 V split-supply. Absolute maximum 12 V. |
| 5 | IN2+ | input | Non-inverting input of op-amp channel 2. Input bias current typ. 200 nA; common-mode range VDD+1.15 V to VCC-1.15 V. |
| 6 | IN2- | input | Inverting input of op-amp channel 2. Input bias current typ. 200 nA; common-mode range VDD+1.15 V to VCC-1.15 V. |
| 7 | OUT2 | output | Output of op-amp channel 2. Rail-to-rail voltage swing. |
| 8 | OUT3 | output | Output of op-amp channel 3. Rail-to-rail voltage swing. |
| 9 | IN3- | input | Inverting input of op-amp channel 3. |
| 10 | IN3+ | input | Non-inverting input of op-amp channel 3. |
| 11 | VCC- | power_in | Negative supply rail / GND for single-supply operation. Tie to 0 V for single-supply, or to -VCC for split-supply operation. |
| 12 | IN4+ | input | Non-inverting input of op-amp channel 4. |
| 13 | IN4- | input | Inverting input of op-amp channel 4. |
| 14 | OUT4 | output | Output of op-amp channel 4. Rail-to-rail voltage swing. |
