SN65HVD72D

The SN65HVD72D is a RS-485 Transceiver, it has robust 3.3V drivers and receivers in a small package for demanding industrial applications. The bus pins are robust to ESD events, with high levels of protection to Human-body Model and IEC Contact Discharge specifications. This device each combine a differential driver and a differential receiver, which operate from a single 3.3V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. This device all feature a wide common-mode voltage range making the devices suitable for multi-point applications over long cable runs.

• ±15kV HBM protection, ±12kV IEC61000-4-2 Contact Discharge Bus I/O Protection
• Large Receiver Hysteresis (80mV) for Noise Rejection
• Low Unit-loading Allows over 200 Connected Nodes
• <lt/>2µA Low Standby Supply Current, ICC <lt/>1mA Quiescent During Operation Low Power Consumption
• 5V Tolerant Logic Inputs Compatible with 3.3 or 5V Controllers
• Signalling Rate Options Optimized for 250kbps, 20Mbps and 50Mbps

Applications

Industrial, Automation & Process Control, Communications & Networking

Warnings

Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
