AM26LV32CD

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

AM26LV32CD from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1B input RS422/RS485 differential input (inverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
2 1A input RS422/RS485 differential input (noninverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
3 1Y tri_state Three-state logic output, VOH 2.4−3.2V, VOL 0.17−0.5V (at IOL=5mA), maximum output current ±25mA.
4 G input Active-high enable select input, VIH≥2V enables receiver output, VIL≤0.8V disables to high-impedance state.
5 2Y tri_state Three-state logic output, VOH 2.4−3.2V, VOL 0.17−0.5V (at IOL=5mA), maximum output current ±25mA.
