SN65HVD20D Description

The transceiver SN65HVD20D offers performance far exceeding typical RS- 485 devices. In addition to meeting all requirements of the TIA/EIA-485-A standard. The SN65HVD20D  operates over an extended range of common-mode voltages and has features such as high ESD protection， wide receiver hysteresis, and failsafe operation. This SN65HVD20D is designed for long-cable networks and other applications where the environment is too harsh for ordinary transceivers.

SN65HVD20D Features

Common-mode voltage range (- 20V to 25 V) more than doubles TIA/EIA-485 requirement

Receiver equalization extends cable length, and signaling rate (SN65HVD2[3,4])

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 (maximum)

More than 100 mV receiver hysteresis
