SN65HVD3085EDR

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

SN65HVD3085EDR 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 Receive data output; transitions high when differential input voltage VID exceeds positive threshold VIT+ and low when VID is below negative threshold VIT-.
2 RE input Receiver enable, active low; receiver output placed in high-impedance state when RE is high or open.
3 DE input Driver enable, active high; driver outputs placed in high-impedance state when DE is low.
4 D input Driver data input; logic high at D produces A output high and B output low when driver is enabled.
5 GND power_in Local device ground reference potential.
6 A bidirectional Differential bus line complementary to B; serves as driver output or receiver input with bus voltage range -7 V to 12 V.
7 B bidirectional Differential bus line complementary to A; serves as driver output or receiver input with bus voltage range -7 V to 12 V.
8 VCC power_in Supply voltage input rated 4.5 V to 5.5 V.
