AM26LV32IDR

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

AM26LV32IDR 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 RS-422/RS-485 differential input (inverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 1A on pin 2.
2 1A input Receiver 1 RS-422/RS-485 differential input (noninverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 1B on pin 1.
3 1Y tri_state Receiver 1 logic-level 3-state output. Drives VOH ≥ 2.4 V at IOH = -5 mA and VOL ≤ 0.5 V at IOL = 5 mA. High-impedance when enables disable the device.
4 G input Active-high output enable common to all four receivers. Logic 1 enables the 3-state Y outputs; VIH ≥ 2 V, VIL ≤ 0.8 V.
5 2Y tri_state Receiver 2 logic-level 3-state output. Drives VOH ≥ 2.4 V at IOH = -5 mA and VOL ≤ 0.5 V at IOL = 5 mA. High-impedance when enables disable the device.
6 2A input Receiver 2 RS-422/RS-485 differential input (noninverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 2B on pin 7.
7 2B input Receiver 2 RS-422/RS-485 differential input (inverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 2A on pin 6.
8 GND power_in Device ground reference. All voltages are measured with respect to this terminal.
9 3B input Receiver 3 RS-422/RS-485 differential input (inverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 3A on pin 10.
10 3A input Receiver 3 RS-422/RS-485 differential input (noninverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 3B on pin 9.
11 3Y tri_state Receiver 3 logic-level 3-state output. Drives VOH ≥ 2.4 V at IOH = -5 mA and VOL ≤ 0.5 V at IOL = 5 mA. High-impedance when enables disable the device.
12 /G input Active-low output enable common to all four receivers. Logic 0 enables the 3-state Y outputs; VIH ≥ 2 V, VIL ≤ 0.8 V. Together with G on pin 4, allows either active-high or active-low enable operation.
13 4Y tri_state Receiver 4 logic-level 3-state output. Drives VOH ≥ 2.4 V at IOH = -5 mA and VOL ≤ 0.5 V at IOL = 5 mA. High-impedance when enables disable the device.
14 4A input Receiver 4 RS-422/RS-485 differential input (noninverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 4B on pin 15.
15 4B input Receiver 4 RS-422/RS-485 differential input (inverting). Common-mode range -0.3 V to 5.5 V; differential threshold ±200 mV typical. Paired with 4A on pin 14.
16 VCC power_in Positive supply voltage. Recommended operating range 3 V to 3.6 V (3.3 V nominal); absolute maximum 6 V. Bypass with a decoupling capacitor to GND.
