TLC272CDR from Texas Instruments, in a SOIC-8. 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 amplifier 1. Rail-to-negative output stage; VOH typ 3.8 V and VOL typ 0 mV at VDD=5 V with RL=10 kΩ. Max output current ±30 mA.
2	1IN-	input	Inverting input of amplifier 1. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail (down to −0.2 V at VDD=5 V).
3	1IN+	input	Non-inverting input of amplifier 1. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail.
4	GND	power_in	Ground / negative supply rail (V−). Single-supply operation referenced to this pin. Total current out of GND up to 45 mA absolute max.
5	2IN+	input	Non-inverting input of amplifier 2. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail.
6	2IN-	input	Inverting input of amplifier 2. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail.
7	2OUT	output	Output of amplifier 2. Rail-to-negative output stage; VOH typ 3.8 V and VOL typ 0 mV at VDD=5 V with RL=10 kΩ. Max output current ±30 mA.
8	VDD	power_in	Positive supply rail. Operating range 3-16 V (C-suffix) or 4-16 V (I/M-suffix); abs max 18 V. Supply current typ 1.4 mA (both amplifiers) at VDD=5 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc272cdr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlc272cdr-etched.step`	1.7 MB	You want the part with `TLC272CDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 432 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
