概述
Description
MC33742PEPR2 is an automotive-grade CAN transceiver from NXP/Freescale. It provides the physical layer between a microcontroller’s CAN controller and the CAN bus, translating TXD/RXD signals to differential CAN_H and CAN_L levels and back. The device integrates fault protection and diagnostics essential for vehicle networks, including undervoltage/overvoltage protection, bus short-circuit protection, thermal protection, ESD, and wake/sleep control. It supports classic CAN (2.0A/B) and is used in ECUs and body electronics where robust, fault-tolerant CAN communication is required. Package variants (such as PEPR2) denote specific RoHS-compliant packaging. For exact electrical specs, pinout, and diagnostic flags, consult the datasheet.
