WIDE SUPPLY RANGE RS-485 TRANSCEIVER

The driver differential outputs and receiver

differential inputs connect internally to form

FEATURES

•

Operates With a 3-V to 5.5-V Supply

differential input/output (I/O) bus port that is designed

to offer minimum loading to the bus whenever the

driver is disabled or not powered. The drivers and

receivers have active-high and active-low enables

respectively, which can be externally connected

together to function as a direction control.

•

Consumes Less Than 90 mW Quiescent

Power

•

Open-Circuit, Short Circuit, and Idle-Bus

Failsafe Receiver

•

1/8^thUnit-Load (up to 256 nodes on the bus)

D or P PACKAGE

(TOP VIEW)

Bus-Pin ESD Protection Exceeds 16 kV HBM

Driver Output Voltage Slew-Rate Limited for

Optimum Signal Quality at 10 Mbps

•

Electrically Compatible With ANSI

TIA/EIA-485 Standard

GND

APPLICATIONS

•

Data Transmission With Remote Stations

Powered From the Host

LOGIC DIAGRAM (Positive Logic)

•

Isolated Multipoint Data Buses

Industrial Process Control Networks

Point-of-Sale Networks

Electric Utility Metering

DESCRIPTION

The SN65HVD08 combines a 3-state differential line

driver and differential line receiver designed for

balanced data transmission and interoperation with

ANSI

TIA/EIA-485-A

and

ISO-8482E

standard-compliant devices.

The wide supply voltage range and low quiescent

current requirements allow the SN65HVD08s to

operate from a 5-V power bus in the cable with as

much as a 2-V line voltage drop. Busing power in the

cable can alleviate the need for isolated power to be

generated at each connection of a ground-isolated

bus.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
