TLV274IDR from Texas Instruments, in a SOIC-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	1OUT	output	Output of op-amp channel 1. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max).
2	1IN-	input	Inverting input, channel 1. High-impedance CMOS input (~1000 GΩ differential, 8 pF common-mode capacitance, ~1 pA input bias current).
3	1IN+	input	Noninverting input, channel 1. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V.
4	VDD	power_in	Positive (highest) supply. Single-supply range 2.7 V to 16 V, or split-supply ±1.35 V to ±8 V. Absolute max 16.5 V.
5	2IN+	input	Noninverting input, channel 2. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V.
6	2IN-	input	Inverting input, channel 2. High-impedance CMOS input (~1000 GΩ differential, ~1 pA input bias current).
7	2OUT	output	Output of op-amp channel 2. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max).
8	3OUT	output	Output of op-amp channel 3. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max).
9	3IN-	input	Inverting input, channel 3. High-impedance CMOS input (~1000 GΩ differential, ~1 pA input bias current).
10	3IN+	input	Noninverting input, channel 3. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V.
11	GND	power_in	Negative (lowest) supply or ground for single-supply operation. All device voltage values (except differential) are referenced to this pin.
12	4IN+	input	Noninverting input, channel 4. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V.
13	4IN-	input	Inverting input, channel 4. High-impedance CMOS input (~1000 GΩ differential, ~1 pA input bias current).
14	4OUT	output	Output of op-amp channel 4. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv274idr.step`	195 KB	You want the bare part, or you mark your own boards.
`tlv274idr-etched.step`	1.7 MB	You want the part with `TLV274IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 463 faces against 237 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.
