SN65HVD75DR

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

SN65HVD75DR from Texas Instruments, in a SOIC-8. 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 R output Receive data output. CMOS-level digital output from the differential receiver; drives the host UART RX line. Follows the A-B bus differential state when the receiver is enabled (RE low).
2 RE input Active-low receiver enable. Drive low to enable the receiver output R; drive high to place R in high-impedance (receiver disabled). 5-V-tolerant logic input.
3 DE input Active-high driver enable. Drive high to enable the differential driver onto the A/B bus; drive low to place A and B in high-impedance. 5-V-tolerant logic input.
4 D input Driver data input. CMOS-level logic input that sets the differential polarity on A/B when the driver is enabled (DE high). 5-V-tolerant logic input.
5 GND power_in Local device ground / reference potential for VCC and all logic and bus signals.
6 A bidirectional RS-485 differential bus I/O, complementary to B. Non-inverting driver output when DE is high; non-inverting receiver input when RE is low. Bus voltage range -13 V to +16.5 V (abs max), common-mode -7 V to +12 V.
7 B bidirectional RS-485 differential bus I/O, complementary to A. Inverting driver output when DE is high; inverting receiver input when RE is low. Bus voltage range -13 V to +16.5 V (abs max), common-mode -7 V to +12 V.
8 VCC power_in Supply voltage input. Recommended 3.0-3.6 V (3.3 V nom); abs max 5 V. Bypass locally to GND.
