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 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.

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 VDD1 or VDD2 = 0 V. Also provided is an
active-high receiver disable feature that causes the receive
output to enter a high impedance state.
The device has current-limiting and thermal shutdown features
to protect against output short circuits and situations where bus
contention may 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.
