What the MAX3053ASA+ is and where it fits
The MAX3053ASA+ is a single-channel CANbus transceiver from Maxim Integrated, handling one driver and one receiver in an 8-SOIC package. It converts the digital CAN controller logic levels to the differential bus signals required by the CAN physical layer, and vice versa. With a data rate of 2 Mbps, it covers standard CAN 2.0B and is commonly used in automotive body electronics, industrial automation networks, and building management systems that operate over a -40°C to 125°C temperature range.
Key ratings and what they mean for your BOM
The 2 Mbps data rate is the maximum signalling speed on the bus. The 150 mV receiver hysteresis filters out noise on the differential bus.
Temperature grade and deployment environment
Rated for -40°C to 125°C, this part is specified for industrial and automotive under-hood environments. The 125°C upper limit covers engine bay or exhaust-adjacent locations; the -40°C low end handles cold-soak starts in northern climates. The 8-SOIC package is a standard footprint, compatible with most pick-and-place lines and reflow profiles for lead-free solder.
Lifecycle and sourcing reality
The MAX3053ASA+ carries an Active product status and is ROHS3 compliant. There is no last-time-buy or obsolescence notice.
