AM26LS32ACDR from Texas Instruments, in a SOIC-16. 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	1B	input	Receiver 1 differential input (inverting). RS-422/RS-485 input with 12 kΩ (min) impedance and ±7 V common-mode range; ±200 mV differential sensitivity with ~50 mV typical hysteresis.
2	1A	input	Receiver 1 differential input (noninverting). RS-422/RS-485 input with 12 kΩ (min) impedance and ±7 V common-mode range; ±200 mV differential sensitivity.
3	1Y	tri_state	Receiver 1 logic-level 3-state output. High when 1A − 1B > +200 mV (or inputs open, fail-safe); high-impedance when disabled by the G/G-bar enables.
4	G	input	Active-high output enable, common to all four receivers. Outputs 1Y-4Y are enabled when G is high AND G-bar (pin 12) is low; otherwise outputs are high-impedance.
5	2Y	tri_state	Receiver 2 logic-level 3-state output. High when 2A − 2B > +200 mV (or inputs open); high-impedance when disabled.
6	2A	input	Receiver 2 differential input (noninverting). RS-422/RS-485 input.
7	2B	input	Receiver 2 differential input (inverting). RS-422/RS-485 input.
8	GND	power_in	Device ground reference. Return for VCC and all logic levels.
9	3B	input	Receiver 3 differential input (inverting). RS-422/RS-485 input.
10	3A	input	Receiver 3 differential input (noninverting). RS-422/RS-485 input.
11	3Y	tri_state	Receiver 3 logic-level 3-state output. High when 3A − 3B > +200 mV (or inputs open); high-impedance when disabled.
12	~G	input	Active-low output enable (shown with overbar in the datasheet), common to all four receivers. Outputs are enabled when this pin is low AND G (pin 4) is high; otherwise outputs are high-impedance.
13	4Y	tri_state	Receiver 4 logic-level 3-state output. High when 4A − 4B > +200 mV (or inputs open); high-impedance when disabled.
14	4A	input	Receiver 4 differential input (noninverting). RS-422/RS-485 input.
15	4B	input	Receiver 4 differential input (inverting). RS-422/RS-485 input.
16	VCC	power_in	Single 5-V supply input (recommended 4.75-5.25 V). Bypass locally to GND with a 0.1 µF ceramic capacitor.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`am26ls32acdr.step`	217 KB	You want the bare part, or you mark your own boards.
`am26ls32acdr-etched.step`	2.9 MB	You want the part with `AM26LS32ACDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 716 faces against 267 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.
