CAN transceiver for 3.3V bus nodes
The Maxim Integrated MAX33054EASA+ is a half-duplex CAN transceiver in an 8-SOIC package, designed to interface a CAN protocol controller with the differential bus lines. It handles signaling at up to 2 Mbps — fast enough for CAN 2.0 and some CAN FD implementations — and operates from a 3V to 3.6V supply rail, which means it is a 3.3V-only part; do not feed it 5V on VCC. The receiver includes 90 mV of hysteresis for noise rejection on the bus, and the -40°C to 125°C temperature range suits it for under-hood automotive modules, industrial motor drives, and outdoor telecom equipment that sees thermal cycling.
Supply voltage and logic-level compatibility
The supply range is 3V to 3.6V, so the part is strictly a 3.3V CAN transceiver. If your controller runs on 5V, you will need level translation on the TXD/RXD pins or choose a 5V-tolerant CAN part. The bus pins (CANH, CANL) are differential and tolerate common-mode voltages well beyond the supply, but the logic interface expects 3.3V signaling levels.
Lifecycle and sourcing posture
This part carries an Active lifecycle status and is ROHS3 compliant — no lead-exemption sunset to track. The laser etch and date-code traceability are maintained through our receiving inspection, so the provenance is clean.
