AM26C32CDBR

Texas Instruments · RS-485/RS-422 ICs · SSOP-16-208mil

AM26C32CDBR from Texas Instruments, in a SSOP-16-208mil. 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 RS422/RS485 differential input of receiver 1; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
2 1A input Noninverting RS422/RS485 differential input of receiver 1; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
3 1Y tri_state Logic-level three-state output of receiver 1; output current is rated ±25 mA (absolute maximum), with 6 mA IOL and -6 mA IOH recommended.
4 G input Active-high select input that enables receivers 1 to 4 when driven high; G inputs are rated -0.5 V to VCC + 0.5 V.
5 2Y tri_state Logic-level three-state output of receiver 2; output current is rated ±25 mA (absolute maximum), with 6 mA IOL and -6 mA IOH recommended.
6 2A input Noninverting RS422/RS485 differential input of receiver 2; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
7 2B input Inverting RS422/RS485 differential input of receiver 2; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
8 GND power_in Ground reference for the device; all voltages except differential voltages are referenced to the network ground terminal.
9 3B input Inverting RS422/RS485 differential input of receiver 3; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
10 3A input Noninverting RS422/RS485 differential input of receiver 3; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
11 3Y tri_state Logic-level three-state output of receiver 3; output current is rated ±25 mA (absolute maximum), with 6 mA IOL and -6 mA IOH recommended.
12 G input Active-low select input that enables receivers 1 to 4 when driven low; G inputs are rated -0.5 V to VCC + 0.5 V.
13 4Y tri_state Logic-level three-state output of receiver 4; output current is rated ±25 mA (absolute maximum), with 6 mA IOL and -6 mA IOH recommended.
14 4A input Noninverting RS422/RS485 differential input of receiver 4; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
15 4B input Inverting RS422/RS485 differential input of receiver 4; the A/B inputs are rated -11 V to 14 V (absolute maximum) with a -7 V to +7 V common-mode range.
16 VCC power_in Power supply; the recommended supply range is 4.5 V to 5.5 V with 5 V nominal.
