Overview
The MAX3051EKA+T is a +3.3V, 1Mbps, low-supply-current CAN (Controller Area Network) transceiver produced by Analog Devices Inc./Maxim Integrated. This component is designed to interface between the CAN protocol controller and the physical wires of the bus lines in a CAN network. It is primarily intended for single-supply applications that do not require the stringent fault protection specified by the automotive industry (ISO 11898). The MAX3051EKA+T is suitable for nonautomotive, harsh environments due to its wide common-mode range and robust protection features.
