SN65HVD34DR

Texas Instruments · RS-485/RS-422 ICs · SOIC-14

SN65HVD34DR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; must be left floating.
2 R output Receive data output (digital output). Driven by the differential receiver comparing bus inputs A and B.
3 RE input Receiver enable, active low (digital input). Drive low to enable the receiver; drive high to place the R output in high-impedance.
4 DE input Driver enable, active high (digital input). Drive high to enable the driver outputs Y and Z; drive low to place them in high-impedance.
5 D input Driver data input (digital input). Logic level presented at D drives the differential Y/Z outputs when DE is asserted.
6 GND power_in Local device ground / reference potential. Pins 6 and 7 are connected together internally.
7 GND power_in Local device ground / reference potential. Pins 6 and 7 are connected together internally.
8 NC unconnected No internal connection; must be left floating.
9 Y output Non-inverting driver bus output (complementary to Z). Together with Z forms the differential RS-485/RS-422 transmit pair.
10 Z output Inverting driver bus output (complementary to Y). Together with Y forms the differential RS-485/RS-422 transmit pair.
11 B input Inverting receiver bus input (complementary to A). Together with A forms the differential RS-485/RS-422 receive pair.
12 A input Non-inverting receiver bus input (complementary to B). Together with B forms the differential RS-485/RS-422 receive pair.
13 VCC power_in 3-V to 3.6-V supply input. Pins 13 and 14 are connected together internally; both must be tied to the supply rail and decoupled.
14 VCC power_in 3-V to 3.6-V supply input. Pins 13 and 14 are connected together internally; both must be tied to the supply rail and decoupled.

CAD (KiCad official)

  • Symbol: SN65HVD34DR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: sn65hvd34dr-etched.step / sn65hvd34dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn65hvd34dr.step / sn65hvd34dr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
