The SN65HVD888 is a low-power RS-485 transceiver
with automatic bus-polarity correction and transient protection. Upon hot plug-in,
the device detects and corrects the bus polarity within the first 76ms of bus
idling. On-chip transient protection protects the device against IEC61000 ESD and
EFT transients. This device has robust drivers and receivers for demanding
industrial applications. The bus pins are robust to electrostatic discharge (ESD)
events, with high levels of protection to Human-Body Model (HBM), Air-Gap Discharge,
and Contact Discharge specifications.
The device combines a differential driver and a
differential receiver, which operate together from a single 5V power supply. The
driver differential outputs and the receiver differential inputs are connected
internally to form a bus port suitable for half-duplex (two-wire bus) communication.
The device features a wide common-mode voltage range making the device suitable for
multi-point applications over long cable runs. The SN65HVD888 is available in an
SOIC-8 package, and is characterized from –40°C to 125°C.
