Product Overview
The device operates from a single 3.3 V nominal supply, with a recommended VCC range of 3 V to 3.6 V. Receiver hysteresis is specified at 80 mV for noise rejection, while supply current is below 1 mA during operation and below 2 µA in low standby mode. Logic inputs are 5-V tolerant, allowing interface to 3.3-V or 5-V controllers.
SN65HVD75DR is supplied in an 8-pin SOIC D package with a 4.91 mm × 3.90 mm nominal body. It is specified for an extended industrial operating temperature range of -40°C to 125°C. Absolute maximum and transient ratings include -13 V to 16.5 V on A or B bus pins, ±100 V transient pulse voltage through 100 Ω, and multiple ESD ratings for all pins or bus pins and GND.
