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. |
