AM26LV32EIDR

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

AM26LV32EIDR 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	Inverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
2	1A	input	Noninverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
3	1Y	output	Logic-level receiver output that is high for VID ≥ 0.2 V and low for VID ≤ −0.2 V, and is high-impedance when the receiver is disabled.
4	G	input	Active-high receiver enable; a logic high enables the outputs, and the enable inputs accept 5-V logic levels with a 3.3-V supply.
5	2Y	output	Logic-level receiver output that is high for VID ≥ 0.2 V and low for VID ≤ −0.2 V, and is high-impedance when the receiver is disabled.
6	2A	input	Noninverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
7	2B	input	Inverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
8	GND	power_in	Network ground; all voltages other than differential input voltage are referenced to this pin.
9	3B	input	Inverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
10	3A	input	Noninverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
11	3Y	output	Logic-level receiver output that is high for VID ≥ 0.2 V and low for VID ≤ −0.2 V, and is high-impedance when the receiver is disabled.
12	G	input	Active-low receiver enable; a logic low enables the outputs, and the enable inputs accept 5-V logic levels with a 3.3-V supply.
13	4Y	output	Logic-level receiver output that is high for VID ≥ 0.2 V and low for VID ≤ −0.2 V, and is high-impedance when the receiver is disabled.
14	4A	input	Noninverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
15	4B	input	Inverting RS-422/RS-485 differential receiver input, sensing down to ±200 mV across a ±7 V common-mode range.
16	VCC	power_in	Single 3.3-V supply pin with a recommended operating range of 3 V to 3.6 V; place a 0.1-µF bypass capacitor close to this pin.
