Product Summary

The SN65HVD22DR is an extended common-mode RS-485 transceiver. It offers performance far exceeding typical RS- 485 devices. The SN65HVD22DR operates over an extended range of common-mode voltage, and has features such as high ESD protection, wide receiver hysteresis, and failsafe operation. The SN65HVD22DR is ideally suited for long-cable networks, and other applications where the environment is too harsh for ordinary transceivers.

Parametrics

SN65HVD22DR absolute maximum ratings: (1)Supply voltage: -0.5V to 7V; (2)Voltage at any bus I/ O terminal: -27 V to 27 V; (3)Voltage input transient pulse: -60 V to 60 V; (4)Receiver output current: -10 mA to 10 mA; (5)Junction temperature: 150℃.
