GENERAL DESCRIPTION

The ADM3054 is a 5 kV rms signal isolated controller area

network (CAN) physical layer transceiver. The ADM3054

complies with the ISO 11898 standard.

The device employs Analog Devices, Inc., iCoupler® technology

to combine a 3-channel isolator and a CAN transceiver into a

single package. The logic side of the device is powered with a

The ADM3054 creates an isolated interface between the CAN

protocol controller and the physical layer bus. It is capable of

running at data rates of up to 1 Mbps.

The device has integrated protection on the bus pins, CANH

and CANL against shorts to power/ground in 24 V systems.

The device has current-limiting and thermal shutdown features

to protect against output short circuits and situations where the

bus might be shorted to ground or power terminals. The part is

fully specified over the industrial temperature range and is

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