Features

Description
The 65/75HVD308xE 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. 65HVD3082E and
75HVD3082E devices are optimized for signaling
rates up to 200 kbps. The 65HVD3085E device is
suitable for data transmission up to 1 Mbps, whereas
the
65HVD3088E
device
is
suitable
for
applications that require 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, which makes these
devices ideal for power-sensitive applications.
The wide common-mode range and high ESD-
protection levels of these devices makes them
suitable for demanding applications such as energy
meter networks, electrical inverters, status and
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 the
HG75176 device. 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 75HVD3082E is characterized for
operation from 0°C to 70°C and 65HVD308xE are
characterized for operation from –40°C to 85°C air
temperature. The D package version of the
65HVD3082E
has been
characterized
for
operation from –40°C to 105°C.
