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℃.
Features
SN65HVD22DR features: (1)Common-Mode Voltage Range (-20 V to 25 V); (2)More Than Doubles TIA/EIA-485 Requirement; (3)Receiver Equalization Extends Cable Length; (4)Reduced Unit-Load for up to 256 Nodes; (5)Bus I/O Protection to Over 16-kV HBM; (6)Failsafe Receiver for Open-Circuit,; (7)Short-Circuit and Idle-Bus Conditions; (8)Low Standby Supply Current 1-μA Max; (9)More Than 100 mV Receiver Hysteresis.
