3 Description
The SNx5HVD1176 devices are half-duplex
differential transceivers with characteristics optimized
for use in PROFIBUS (EN 50170) applications. The
driver output differential voltage exceeds the
PROFIBUS requirements of 2.1 V with a 54-load. A
signaling rate of up to 40 Mbps allows technology
growth to high data-transfer speeds. The low bus
capacitance provides low signal distortion.
The SN65HVD1176 and SN75HVD1176 devices
meet or exceed the requirements of ANSI standard
TIA/EIA-485-A (RS-485) for differential data
transmission across twisted-pair networks. The driver
outputs and receiver inputs are tied together to form a
half-duplex bus port with one-fifth unit load, which
allows up to 160 nodes on a single bus. The receiver
output stays at logic high when the bus lines are
shorted, left open, or when no driver is active. The
driver outputs are in high impedance when the supply
voltage is below 2.5 V to prevent bus disturbance
during power cycling or during live insertion to the
bus. An internal current limit protects the transceiver
bus pins in short-circuit fault conditions by limiting the
output current to a constant value. Thermal shutdown
circuitry protects the device against damage due to
excessive power dissipation caused by faulty loading
and drive conditions.
The SN75HVD1176 device is characterized for
operation at temperatures from 0°C to 70°C. The
SN65HVD1176 device is characterized for operation
at temperatures from –40°C to 85°C.
For an isolated version of this device, see the
ISO1176 device (SLLS897) with integrated digital
isolators.
