WIDE SUPPLY RANGE RS-485 TRANSCEIVER

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.

FEATURES

•

Operates With a 3-V to 5.5-V Supply

•

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)

The driver differential outputs and receiver differential

inputs connect internally to form a differential in-

put/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 func-

tion as a direction control.

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

DESCRIPTION

The SN65HVD08 combines a 3-state differential line

driver and differential line receiver designed for bal-

anced data transmission and interoperation with ANSI

TIA/EIA-485-A and ISO-8482E standard-compliant

devices.
