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
