GENERAL DESCRIPTION
The ADM2490E is an isolated data transceiver with ±8 kV ESD
protection that is suitable for high speed, full-duplex communi-
cation on multipoint transmission lines. It is designed for balanced
transmission lines and complies with ANSI TIA/EIA-485-A-1998
and ISO 8482: 1987(E). The device employs Analog Devices, Inc.,
iCoupler technology to combine a 2-channel isolator, a three-
state differential line driver, and a differential input receiver into
a single package.
The differential transmitter outputs and receiver inputs feature
electrostatic discharge circuitry that provides protection to ±8 kV
using the human body model (HBM). The logic side of the device
can be powered with either a 5 V or a 3 V supply, whereas the
bus side requires an isolated 5 V supply.
The device has current-limiting and thermal shutdown features
to protect against output short circuits and situations where bus
contention could cause excessive power dissipation.
The ADM2490E is available in a wide body, 16-lead SOIC package
and operates over the 40°C to +105°C temperature range.
