APPLICATIONS

Low power RS-485 applications

EMI sensitive systems

DTE-DCE interfaces

Industrial control

Packet switching

Local area networks

Level translators

The receiver input impedance is 96 kΩ, allowing up to 256

transceivers to be connected on the bus. A thermal shutdown

circuit prevents excessive power dissipation caused by bus

contention or by output shorting. If a significant temperature

increase is detected in the internal driver circuitry during fault

conditions then the thermal shutdown circuit forces the driver

output into a high impedance state. The receiver contains a fail-

safe feature that results in a logic high output state, if the inputs

are unconnected (floating).

GENERAL DESCRIPTION

The ADM3493 is a low power, differential line transceiver

designed to operate using a single 3.3 V power supply. Low

power consumption, coupled with a shutdown mode, makes it

ideal for power-sensitive applications. The ADM3493 is suitable

for communication on multipoint bus transmission lines.

The device contains one driver and one receiver. Designed for

half-duplex communication, the ADM3493 features a slew rate

limited driver that minimizes EMI and reduces reflections

caused by improperly terminated cables, allowing error-free

data transmission at data rates up to 250 kbps.

The ADM3493 is fully specified over the commercial and

industrial temperature ranges and is available in an 8-lead SOIC.
