SN65HVD22P from Texas Instruments, in a PDIP-8. 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 | R | output | Receive data output from the receiver; the receiver output current is limited to ±10 mA (absolute maximum). |
| 2 | RE | input | Receiver enable, active low; logic-input thresholds are VIL 0.8 V maximum and VIH 2 VCC minimum, with input voltage limited to -0.5 V to VCC + 0.5 V. |
| 3 | DE | input | Driver enable, active high; logic-input thresholds are VIL 0.8 V maximum and VIH 2 VCC minimum, with input voltage limited to -0.5 V to VCC + 0.5 V. |
| 4 | D | input | Driver data input; logic-input thresholds are VIL 0.8 V maximum and VIH 2 VCC minimum, with input voltage limited to -0.5 V to VCC + 0.5 V. |
| 5 | GND | power_in | Local device ground and reference potential for the device; all voltages except differential bus voltages are referenced to the network ground terminal. |
| 6 | A | bidirectional | Bus I/O: driver output or receiver input, complementary to B; the recommended bus I/O voltage range is -20 V to 25 V and the absolute maximum is -27 V to 27 V. |
| 7 | B | bidirectional | Bus I/O: driver output or receiver input, complementary to A; the recommended bus I/O voltage range is -20 V to 25 V and the absolute maximum is -27 V to 27 V. |
| 8 | VCC | power_in | Supply pin; the recommended supply range is 4.5 V to 5.5 V (5 V nominal). |
