TS974IYPT

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.
