SN75HVD3082EDGKR

Texas Instruments · RS-485 / RS-422 ICs · VSSOP-8-0.65mm

SN75HVD3082EDGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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. Digital CMOS output that reflects the differential state of the A/B bus inputs when the receiver is enabled (RE low).
2 RE input Receiver enable, active low. Drive low to enable the receive path (R output active); drive high to place R in a high-impedance state. Driving RE high and DE low places the device in low-power shutdown.
3 DE input Driver enable, active high. Drive high to enable the differential bus driver; drive low to place the A/B outputs in a high-impedance state. Driving DE low with RE high enters shutdown mode.
4 D input Driver data input. Digital CMOS input; when the driver is enabled, a logic high on D drives A high and B low, and a logic low drives A low and B high.
5 GND power_in Local device ground / reference potential. Connect to the system ground plane close to the VCC decoupling capacitor.
6 A bidirectional RS-485 differential bus line A: non-inverting driver output and non-inverting receiver input (complementary to B). Connect to one wire of the twisted-pair bus; typically terminated with 120-Ω at each end of the cable.
7 B bidirectional RS-485 differential bus line B: inverting driver output and inverting receiver input (complementary to A). Connect to the second wire of the twisted-pair bus.
8 VCC power_in Positive supply, 4.5 V to 5.5 V. Decouple with a 100-nF ceramic capacitor to GND placed close to the pin.
