Low-Power RS-485 Transceivers, Available in a Small MSOP-8

Package

FEATURES

DESCRIPTION

• Available in a Small MSOP-8 Package

These devices are half-duplex transceivers designed

• Meets or Exceeds the Requirements of the

for RS–485 data bus networks. Powered by a 5–V

TIA/EIA−485A Standard

supply, they are fully compliant with TIA/EIA-485A

• Low Quiescent Power

standard. With controlled transition times, these

devices are suitable for transmitting data over long

– 0.3 mA Active Mode

twisted-pair cables. SN65HVD3082E and

– 1 nA Shutdown Mode

SN75HVD3082E devices are optimized for signaling

• 1/8 Unit Load—Up to 256 Nodes on a Bus

rates up to 200 kbps. SN65HVD3085E is suitable for

data transmission up to 1 Mbps, whereas

• Bus-Pin ESD Protection Up to 15 kV

SN65HVD3088E is suitable for applications requiring

• Industry-Standard SN75176 Footprint

signaling rates up to 20 Mbps. These devices are

• Failsafe Receiver (Bus Open, Bus Shorted,

designed to operate with very low supply current,

Bus Idle)

typically 0.3 mA, exclusive of the load. When in the

inactive shutdown mode, the supply current drops to

• Glitch–Free Power–Up/Down Bus Inputs and

a few nanoamps, making these devices ideal for

Outputs

power-sensitive applications.

APPLICATIONS

The wide common-mode range and high ESD

protection levels of these devices make them suitable

• Energy Meter Networks

for demanding applications such as energy meter

• Motor Control

networks, electrical inverters, status/command signals

• Power Inverters

across telecom racks, cabled chassis interconnects,

and industrial automation networks where noise

• Industrial Automation

tolerance is essential. These devices match the

• Building Automation Networks

industry-standard footprint of SN75176. Power-on

• Battery-Powered Applications

reset circuits keep the outputs in a high impedance

state until the supply voltage has stabilized. A thermal

• Telecommunications Equipment

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.

To comply with the RS-422 and RS-485 standards, the receiver output must output a High when the differential input VID is more positive than +200 mV, and must output a Low when the VID is more negative than -200 mV.

Power supply current is delivered to the bus load as well as to the transceiver circuitry. For a typical RS–485 bus configuration, the load that an active driver must drive consists of all of the receiving nodes, plus the termination resistors at each end of the bus.
