MC33074ADTBR2G from onsemi, 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	Amplifier 1 output. All-NPN output stage sourcing/sinking up to 30 mA typ (10 mA source / 20 mA sink min short-circuit). Swings to within ~1.0 V of VCC and ~0.3 V of VEE with 10 kΩ load.
2	In-1	input	Amplifier 1 inverting input. Bipolar Darlington input; IIB ≈ 100 nA typ, differential input resistance ~150 MΩ, input capacitance ~2.5 pF.
3	In+1	input	Amplifier 1 non-inverting input. Common-mode range includes VEE up to (VCC − 1.8 V); do not exceed VCC or drive below VEE − 0.3 V.
4	VCC	power_in	Positive supply rail. Single-supply operation 3.0 V to 44 V, or split supplies with VCC +
5	In+2	input	Amplifier 2 non-inverting input. Same VICR/IIB characteristics as amplifier 1.
6	In-2	input	Amplifier 2 inverting input. Bipolar Darlington input; IIB ≈ 100 nA typ.
7	Output 2	output	Amplifier 2 output. All-NPN output stage, 30 Ω typ open-loop output impedance at 1 MHz; drives 0 pF to 10,000 pF capacitive loads without oscillation in unity gain.
8	Output 3	output	Amplifier 3 output. All-NPN output stage; 20 mA min sink capability typically to (VEE + 1.8 V).
9	In-3	input	Amplifier 3 inverting input. Bipolar Darlington input stage; ESD-protected input diodes/clamps.
10	In+3	input	Amplifier 3 non-inverting input. Common-mode input voltage range VEE to (VCC − 1.8 V) at 25 °C.
11	VEE	power_in	Negative supply / ground return. Tie to ground for single-supply operation (3.0 V to 44 V at VCC) or to a negative rail for split supplies. VCC to VEE differential must not exceed +44 V.
12	In+4	input	Amplifier 4 non-inverting input. Same input characteristics as the other channels.
13	In-4	input	Amplifier 4 inverting input. Bipolar Darlington input; VIO ≤ 3.0 mV max (A suffix) at 25 °C.
14	Output 4	output	Amplifier 4 output. All-NPN output stage; short-circuit protected indefinitely to ground at ±15 V supplies.
