SN65HVD22P

Texas Instruments · RS-485 / RS-422 ICs · PDIP-8

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).
