DESCRIPTION
These devices are half-duplex transceivers designed
for RS–485 data bus networks. Powered by a 5–V
supply, they are fully compliant with TIA/EIA-485A
standard. With controlled transition times, these
devices are suitable for transmitting data over long
twisted-pair cables. SN65HVD3082E and
SN75HVD3082E devices are optimized for signaling
rates up to 200 kbps. SN65HVD3085E is suitable for
data transmission up to 1 Mbps, whereas
SN65HVD3088E is suitable for applications requiring
signaling rates up to 20 Mbps. These devices are
designed to operate with very low supply current,
typically 0.3 mA, exclusive of the load. When in the
inactive shutdown mode, the supply current drops to
a few nanoamps, making these devices ideal for
power-sensitive applications.
The wide common-mode range and high ESD
protection levels of these devices make them suitable
for demanding applications such as energy meter
networks, electrical inverters, status/command signals
across telecom racks, cabled chassis interconnects,
and industrial automation networks where noise
tolerance is essential. These devices match the
industry-standard footprint of SN75176. Power-on
reset circuits keep the outputs in a high impedance
state until the supply voltage has stabilized. A thermal
shutdown function protects the device from damage
due to system fault conditions. The SN75HVD3082E
is characterized for operation from 0°C to 70°C and
SN65HVD308xE are characterized for operation from
–40°C to 85°C air temperature.
