AM26LS32AIDR

Texas Instruments · RS-485 / RS-422 ICs · SOIC-16

AM26LS32AIDR 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 Channel 1 RS-422/RS-485 differential input (inverting). Input impedance ≥12 kΩ. Common-mode range ±7 V with ±200 mV sensitivity.
2 1A input Channel 1 RS-422/RS-485 differential input (noninverting). Input impedance ≥12 kΩ. Common-mode range ±7 V with ±200 mV sensitivity.
3 1Y tri_state Channel 1 logic-level (single-ended CMOS/TTL) receiver output. 3-state; disabled when G is low or G-bar is high. IOH = -440 µA, IOL = 8 mA.
4 G input Active-high output enable. When G is high (and G-bar is low), all four Y outputs are enabled; otherwise outputs are high-impedance.
5 2Y tri_state Channel 2 logic-level receiver output. 3-state; controlled by G / G-bar enables.
6 2A input Channel 2 RS-422/RS-485 differential input (noninverting). Input impedance ≥12 kΩ.
7 2B input Channel 2 RS-422/RS-485 differential input (inverting). Input impedance ≥12 kΩ.
8 GND power_in Device ground / negative supply reference.
9 3B input Channel 3 RS-422/RS-485 differential input (inverting). Input impedance ≥12 kΩ.
10 3A input Channel 3 RS-422/RS-485 differential input (noninverting). Input impedance ≥12 kΩ.
11 3Y tri_state Channel 3 logic-level receiver output. 3-state; controlled by G / G-bar enables.
12 ~{G} input Active-low output enable (G-bar). When G-bar is low (and G is high), all four Y outputs are enabled; otherwise outputs are high-impedance.
13 4Y tri_state Channel 4 logic-level receiver output. 3-state; controlled by G / G-bar enables.
14 4A input Channel 4 RS-422/RS-485 differential input (noninverting). Input impedance ≥12 kΩ.
15 4B input Channel 4 RS-422/RS-485 differential input (inverting). Input impedance ≥12 kΩ.
16 VCC power_in Positive supply. 4.75 V to 5.25 V (AM26LS32AI industrial grade); 5 V nominal.

CAD (KiCad official)

  • Symbol: AM26LS32AIDR
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOIC-16 (KiCad packages3D, STEP)
  • 3D model files: am26ls32aidr-etched.step / am26ls32aidr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); am26ls32aidr.step / am26ls32aidr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
am26ls32aidr.step 217 KB You want the bare part, or you mark your own boards.
am26ls32aidr-etched.step 2.8 MB You want the part with AM26LS32AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 704 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.
