TS974IPT 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	Output 1	output	Op-amp 1 output. Rail-to-rail output stage swings within ~100 mV of VDD/VCC; short-circuit protected.
2	Inverting input 1	input	Op-amp 1 inverting input (IN−). Common-mode range VDD+1.15 V to VCC−1.15 V; do not exceed VDD−0.3 V or VCC+0.3 V.
3	Non-inverting input 1	input	Op-amp 1 non-inverting input (IN+). Same input constraints as IN−.
4	VCC	power_in	Positive supply. Operating range 2.7 V to 10 V single-supply (or up to ±5 V split-supply). Absolute max 12 V.
5	Non-inverting input 2	input	Op-amp 2 non-inverting input (IN+).
6	Inverting input 2	input	Op-amp 2 inverting input (IN−).
7	Output 2	output	Op-amp 2 output. Rail-to-rail; short-circuit protected.
8	Output 3	output	Op-amp 3 output. Rail-to-rail; short-circuit protected.
9	Inverting input 3	input	Op-amp 3 inverting input (IN−).
10	Non-inverting input 3	input	Op-amp 3 non-inverting input (IN+).
11	VDD	power_in	Negative supply / ground reference. Tie to GND for single-supply operation, or to the negative rail for split-supply operation.
12	Non-inverting input 4	input	Op-amp 4 non-inverting input (IN+).
13	Inverting input 4	input	Op-amp 4 inverting input (IN−).
14	Output 4	output	Op-amp 4 output. Rail-to-rail; short-circuit protected.
