Automotive Environments

• Automatic Thermal Shutdown Protection

• Suitable for 12V and 24V Systems

• Meets or exceeds stringent automotive design

requirements including “Hardware Requirements

for LIN, CAN and FlexRay Interfaces in Automo-

tive Applications”, Version 1.3, May 2012

• High-Noise Immunity Due to Differential Bus

Implementation

• High ESD Protection on CANH and CANL, Meets

IEC61000-4-2 greater ±8 kV

• Available in PDIP-8L, SOIC-8L and 3x3 DFN-8L

- High (H): -40°C to +150°C

Description:

The MCP2561/2 is a Microchip Technology Inc. second

generation high-speed CAN transceiver. It serves as an

interface between a CAN protocol controller and the

physical two-wire CAN bus.

The device meets the automotive requirements for

high-speed (up to 1 Mb/s), low quiescent current,

electromagnetic compatibility (EMC) and electrostatic

discharge (ESD).
