3 Description

The SNx5HVD308xE 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. The SN65HVD3082E and

SN75HVD3082E are optimized for signaling rates

up to 200 kbps. The SN65HVD3085E is suitable

for data transmission up to 1 Mbps, whereas the

SN65HVD3088E 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, make them suitable

for demanding applications such as energy meter

networks, electrical inverters, status and command

signals across telecom racks, as well as cabled

chassis interconnects, and industrial automation

networks where noise tolerance is essential. These

devices match the industry-standard footprint of the

SN75176 device. The 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 is characterized for operation from –

40°C to 85°C air temperature. The D package version

of the SN65HVD3082E has been characterized for

operation from –40°C to 105°C.
