The driver • High Receiver Hysteresis for Noise Immunity differential outputs and the receiver differential inputs (60 mV Typical) are separate pins, to form a bus port for full-duplex (four-wire) communications. The driver and receiver • 1/8 Unit-Load (Up to 256 Nodes on the Bus) can be independently enabled, and feature a wide • Bus-pin ESD Protection Exceeds 15 kV HBM common-mode voltage range, making this device • Driver Output Transition Times Optimized for suitable for multi-point applications over long cable Signaling Rate up to 20 Mbps runs. The SN65HVD37 is characterized over the temperature range of -40 ºC to 85 ºC. • Glitch-Free Power-Up and Power-Down Protection for Hot-Plugging Applications • 5V-Tolerant Logic Inputs • Bus Idle, Open, and Short-Circuit Failsafe • Driver Current Limiting and Thermal Shutdown • Fully Meets All TIA-485-A Specifications APPLICATIONS • Telecommunications Equipment • Industrial Automation • Process Automation • Building Automation • Point-of-Sale (POS) Terminals • Improved Replacement for ADM3076, ADM3491, LTC2852, MAX3491 and SP3491 Figure 1. 60 mV Receiver Hysteresis for Noise Immunity 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
