_IORM= 560 V peak

Operating temperature range: −40°C to +85°C

Wide body, 16-lead SOIC package

The device employs Analog Devices’ iCoupler technology to

combine a 3-channel isolator, a three-state differential line

driver, and a differential input receiver into a single package.

The logic side of the device is powered with either a 5 V or a

3 V supply, and the bus side uses an isolated 5 V supply.

APPLICATIONS

The ADM2486 driver has an active-high enable feature. The

driver differential outputs and the receiver differential inputs

are connected internally to form a differential input/output port

that imposes minimal loading on the bus when the driver is

disabled or when V_DD1or V_DD2= 0 V. Also provided is an active-

high receiver disable feature that causes the receive output to

enter a high impedance state.

GENERAL DESCRIPTION

The ADM2486 differential bus transceiver is an integrated,

galvanically isolated component designed for bidirectional

data communication on multipoint bus transmission lines. It

is designed for balanced transmission lines and complies with

ANSI EIA/TIA-485-A and ISO 8482: 1987(E).

The device has current-limiting and thermal shutdown features

to protect against output short circuits and situations where bus

contention might cause excessive power dissipation. The part is

fully specified over the industrial temperature range and is

available in a 16-lead, wide body SOIC package.
