The MAX13021ASA+ is a LINbus transceiver from Analog Devices, built for single-wire Local Interconnect Network nodes in automotive body electronics, industrial sensor buses, and control modules. The supply range of 5V to 38V covers both 12V automotive and 24V truck/industrial rails without an external regulator.
Ratings that decide the fit
The 5V to 38V supply range is the standout spec here. Most LIN transceivers top out at 18V or 27V; this one handles 38V, which means it survives load-dump transients on a 24V truck system without a clamp. Full duplex with 1/1 driver/receiver is standard for LIN, but the wide supply and temperature grade are what separate this part from a commodity part.
No NRND or EOL notice is on record.
