THVD1439DR

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

THVD1439DR from Texas Instruments, in a SOIC-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 Receiver data output; the absolute maximum receiver output current is ±24 mA.
2 RE input Receiver enable, active low, with a 2 MΩ internal pull-up.
3 DE input Driver enable, active high.
4 D input Driver data input; the absolute maximum logic input range is -0.3 V to 5.7 V for THVD1439 and THVD1449.
5 GND power_in Device ground.
6 A bidirectional Bus I/O port A, complementary to B; the absolute maximum bus voltage range at A or B is -15 V to 15 V.
7 B bidirectional Bus I/O port B, complementary to A; the absolute maximum bus voltage range at A or B is -15 V to 15 V.
8 VCC power_in 3.3-V to 5-V supply for the device; the absolute maximum supply voltage is 7 V.
