SN65HVD1782DR

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

SN65HVD1782DR 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 providing decoded differential bus state
2 RE input Receiver enable low-active input; receiver enabled when RE is logic low
3 DE input Driver enable high-active input; driver enabled when DE is logic high
4 D input Driver data input controlling differential output states when driver is enabled
5 GND power_in Ground reference potential for device operation
6 A bidirectional Differential bus pin A for driver output or receiver input, complementary to B, absolute maximum rating -70 to +30 V
7 B bidirectional Differential bus pin B for driver output or receiver input, complementary to A, absolute maximum rating -70 to +30 V
8 VCC power_in Supply voltage for device operation in 4.5-V to 5.5-V range
