Product Overview
The SN65HVD75 is a Texas Instruments 3.3-V RS-485 transceiver in the Signal_Chain category. It supports half-duplex two-wire bus communication and uses separate DE and RE enable pins for driver and receiver control. The device comparison data lists a 20 Mbps maximum signaling rate and half-duplex operation.
The VCC supply operating range is 3 V to 3.6 V, while logic inputs are 5 V tolerant for compatibility with 3.3-V or 5-V controllers. Receiver hysteresis is specified at 80 mV for noise rejection. Supply-current facts include less than 1 mA quiescent supply current during operation and less than 2 µA standby supply current in low-power standby mode.
Package options include SOIC-8 4.91 mm x 3.90 mm, VSSOP-8 3.00 mm x 3.00 mm, and VSON-8 3.00 mm x 3.00 mm. The pinout provides R receive data output, RE active-low receiver enable, DE active-high driver enable, D driver data input, GND, complementary A and B bus I/O pins, and VCC supply.
