DS96176

RS-485/RS-422 Differential Bus Transceiver

General Description

The DS96176 Differential Bus Transceiver is a monolithic in-

tegrated circuit designed for bidirectional data communica-

tion on balanced multipoint bus transmission lines. The

transceiver meets EIA Standard RS-485 as well as

RS-422A.

The DS96176 combines a TRI-STATE

and a differential input line receiver, both of which operate

from a single 5.0V power supply. The driver and receiver

have an active Enable that can be externally connected to

function as a direction control. The driver differential outputs

and the receiver differential inputs are internally connected

to form differential input/output (I/O) bus ports that are de-

signed to offer minimum loading to the bus whenever the

driver is disabled or when V

wide positive and negative common mode voltage ranges,

making the device suitable for multipoint applications in

noisy environments.

The driver is designed to handle loads up to 60 mA of sink or

source current. The driver features positive and negative

current-limiting and thermal shutdown for protection from line

fault conditions. Thermal shutdown is designed to occur at

junction temperature of approximately 160˚C. The receiver

features a typical input impedance of 15 k , an input sensi-

tivity of

The DS96176 can be used in transmission line applications

employing the DS96172 and the DS96174 quad differential

line drivers and the DS96173 and DS96175 quad differential

line receivers.
