LM293DR 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	Open-collector output of comparator 1. Requires an external pull-up resistor to VCC (typical 5.1 kΩ). Sinks up to 6 mA (min) / 21 mA (typ) with VOL ≤ 1.5 V; low-level output voltage ≤ 400 mV at ISINK = 4 mA.
2	1IN-	input	Inverting (negative) input of comparator 1. Common-mode input range extends from V- (ground) to (V+) - 1.5 V. Differential input voltage up to ±36 V; input bias current typically -25 nA.
3	1IN+	input	Non-inverting (positive) input of comparator 1. Common-mode input range includes ground. Input bias current typically -25 nA; must not go more than 0.3 V below V-.
4	GND	power_in	Ground / negative supply (V-). For single-supply operation, connect to system ground.
5	2IN+	input	Non-inverting (positive) input of comparator 2. Common-mode input range includes ground; input bias current typically -25 nA.
6	2IN-	input	Inverting (negative) input of comparator 2. Common-mode input range V- to (V+) - 1.5 V; differential input voltage up to ±36 V.
7	2OUT	output	Open-collector output of comparator 2. Requires an external pull-up resistor to VCC. Sinks up to 6 mA (min) with VOL ≤ 1.5 V; compatible with TTL, MOS, and CMOS logic.
8	VCC	power_in	Positive supply (V+). Operating range 2 V to 30 V (LM293); absolute maximum 36 V. Quiescent current typically 0.45 mA at VCC = 5 V. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm293dr.step`	122 KB	You want the bare part, or you mark your own boards.
`lm293dr-etched.step`	1.7 MB	You want the part with `LM293DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 417 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.
