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.
6	2A	input	RS422/RS485 differential input (noninverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
7	2B	input	RS422/RS485 differential input (inverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
8	GND	power_in	Ground connection, voltage reference for all signal measurements.
9	3B	input	RS422/RS485 differential input (inverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
10	3A	input	RS422/RS485 differential input (noninverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
11	3Y	tri_state	Three-state logic output, VOH 2.4−3.2V, VOL 0.17−0.5V (at IOL=5mA), maximum output current ±25mA.
12	G	input	Active-low enable select input (complementary to pin 4), VIL≤0.8V enables receiver output, VIH≥2V disables to high-impedance state.
13	4Y	tri_state	Three-state logic output, VOH 2.4−3.2V, VOL 0.17−0.5V (at IOL=5mA), maximum output current ±25mA.
14	4A	input	RS422/RS485 differential input (noninverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
15	4B	input	RS422/RS485 differential input (inverting), accepts −0.3V to 5.5V common-mode and ±5.8V differential input voltage.
16	VCC	power_in	Power supply input, 3.0−3.6V recommended (nominal 3.3V), typical supply current 8−17mA with line inputs open.
