At 1 Mbps, the propagation delay budget leaves margin for a few meters of cable before the round-trip timing closes the window for collision detection or token passing. ## Temperature range and deployment context The 8-SOIC package's thermal impedance (junction-to-ambient ~120°C/W typical) keeps the die within limits at the 1 Mbps switching rate with a 3.6V supply.","metaTitle":"SN65HVD32DG4 RS485/RS422 Transceiver, Full Duplex, 1Mbps","metaDescription":"Texas Instruments SN65HVD32DG4 RS422/RS485 full-duplex transceiver, 1 Mbps, 3V-3.6V supply, 8-SOIC, -40°C to 85°C.

The receiver hysteresis of 50 mV and the driver differential output meet RS485 levels at 3.3V without external biasing."},{"question":"What is the pinout of SN65HVD32DG4?","answer":"The 8-SOIC pinout follows the standard RS485 transceiver assignment: pin 1 (RO), pin 2 (RE), pin 3 (DE), pin 4 (DI), pin 5 (GND), pin 6 (A), pin 7 (B), pin 8 (VCC). The full-duplex bus pins A and B are the differential pair; RO and DI are the receiver output and driver input, respectively."},{"question":"Is SN65HVD32DG4 RoHS compliant?","answer":"Yes, the SN65HVD32DG4 is RoHS compliant per Texas Instruments' standard green packaging.
