Overview
The transceivers in the HVD2x family offer performance far exceeding typical
RS-485 devices. In addition to meeting all requirements of the TIA/EIA-485-A
standard, the HVD2x family operates over an extended range common-mode
voltage, and has features such as high ESD protection, wide receiver
hysteresis, and failsafe operation. This family of devices is ideally suited for
long-cable networks and other applications where the environment is too
harsh for ordinary transceivers.
These devices are designed for bidirectional data transmission on multipoint
twisted-pair cables. Example applications are digital motor controllers, remote
sensors and terminals, industrial process control, security stations, and
environmental control systems.
These devices combine a 3-state differential driver and a differential receiver,
which operate from a single 5-V power supply. The driver differential outputs
and the receiver differential inputs are connected internally to form a
differential bus port that offers minimum loading to the bus. This port features
an extended common-mode voltage range making the device suitable for
multipoint applications over long cable runs. Figure 1-1 shows the basic
functions of the SN65HVD22.
The SN65HVD22 has controlled driver output slew rate for low radiated noise
in emission-sensitive applications and for improved signal quality with long
stubs. Up to 256 SN65HVD22 nodes can be connected at signaling rates up
to 500 kbps.
