SN65HVD21A
Description
The SN65HVD21A offers performance far exceeding typical RS-485 devices. In addition to meeting all requirements of the TIA/EIA-485-A standard, the device operates over an extended range of common-mode voltage, and has features such as high ESD protection, wide receiver hysteresis, and failsafe operation.
Key Features
- Common-Mode Voltage Range (-20 V to 25 V) More Than Doubles TIA/EIA-485 Requirement
- Reduced Unit-Load for up to 256 Nodes
- Bus I/O Protection to Over 16-kV HBM
- Failsafe Receiver for Open-Circuit, Short-Circuit and Idle-Bus Conditions
- Low Standby Supply Current 1-µA Max
- More Than 100 mV Receiver Hysteresis
