AM26C32IDR

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

AM26C32IDR 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 inverting input (RS-422/RS-485 B-side). Common-mode range ±7 V; ±200 mV sensitivity; input resistance ~12-17 kΩ.
2 1A input Receiver 1 differential noninverting input (RS-422/RS-485 A-side). Common-mode range ±7 V; ±200 mV sensitivity; input resistance ~12-17 kΩ.
3 1Y tri_state Receiver 1 logic-level 3-state output. Drives VOH ≥ 3.8 V at -6 mA, VOL ≤ 0.3 V at 6 mA; high-Z when disabled by G/G-bar.
4 G input Active-high output enable common to all four receivers. When G=H and G-bar=L, outputs are enabled; otherwise outputs are in high-impedance state.
5 2Y tri_state Receiver 2 logic-level 3-state output. Drives VOH ≥ 3.8 V at -6 mA, VOL ≤ 0.3 V at 6 mA; high-Z when disabled.
6 2A input Receiver 2 differential noninverting input (RS-422/RS-485 A-side). Common-mode range ±7 V; ±200 mV sensitivity.
7 2B input Receiver 2 differential inverting input (RS-422/RS-485 B-side). Common-mode range ±7 V; ±200 mV sensitivity.
8 GND power_in Device ground reference. All voltages are referenced to this network ground terminal.
9 3B input Receiver 3 differential inverting input (RS-422/RS-485 B-side). Common-mode range ±7 V; ±200 mV sensitivity.
10 3A input Receiver 3 differential noninverting input (RS-422/RS-485 A-side). Common-mode range ±7 V; ±200 mV sensitivity.
11 3Y tri_state Receiver 3 logic-level 3-state output. Drives VOH ≥ 3.8 V at -6 mA, VOL ≤ 0.3 V at 6 mA; high-Z when disabled.
12 ~{G} input Active-low output enable common to all four receivers. When G-bar=L and G=H, outputs are enabled; otherwise outputs are in high-impedance state.
13 4Y tri_state Receiver 4 logic-level 3-state output. Drives VOH ≥ 3.8 V at -6 mA, VOL ≤ 0.3 V at 6 mA; high-Z when disabled.
14 4A input Receiver 4 differential noninverting input (RS-422/RS-485 A-side). Common-mode range ±7 V; ±200 mV sensitivity.
15 4B input Receiver 4 differential inverting input (RS-422/RS-485 B-side). Common-mode range ±7 V; ±200 mV sensitivity.
16 VCC power_in Positive supply input. Recommended 4.5 V to 5.5 V (nominal 5 V); Icc ≈ 10 mA typical, 15 mA max. Absolute max 7 V.
