AM26C32QDR

Texas Instruments · Interface - Specialized · SOIC-16

AM26C32QDR 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) for receiver 1, with ±7 V common-mode range and ±200 mV sensitivity.
2 1A input RS422/RS485 differential input (noninverting) for receiver 1, with ±7 V common-mode range and ±200 mV sensitivity.
3 1Y output Logic level output of receiver 1, three-state, high when input is open (fail-safe).
4 G input Active-high enable (select) input shared by the receivers; a high level enables the outputs.
5 2Y output Logic level output of receiver 2, three-state, high when input is open (fail-safe).
6 2A input RS422/RS485 differential input (noninverting) for receiver 2, with ±7 V common-mode range and ±200 mV sensitivity.
7 2B input RS422/RS485 differential input (inverting) for receiver 2, with ±7 V common-mode range and ±200 mV sensitivity.
8 GND power_in Ground.
9 3B input RS422/RS485 differential input (inverting) for receiver 3, with ±7 V common-mode range and ±200 mV sensitivity.
10 3A input RS422/RS485 differential input (noninverting) for receiver 3, with ±7 V common-mode range and ±200 mV sensitivity.
11 3Y output Logic level output of receiver 3, three-state, high when input is open (fail-safe).
12 ~{G} input Active-low enable (select) input shared by the receivers; a low level enables the outputs.
13 4Y output Logic level output of receiver 4, three-state, high when input is open (fail-safe).
14 4A input RS422/RS485 differential input (noninverting) for receiver 4, with ±7 V common-mode range and ±200 mV sensitivity.
15 4B input RS422/RS485 differential input (inverting) for receiver 4, with ±7 V common-mode range and ±200 mV sensitivity.
16 VCC power_in Power supply, 4.5 V to 5.5 V recommended (7 V absolute maximum), bypassed with a 0.1 µF capacitor.
