What this 3.3V transceiver buys you on a 5V-heavy BOM
The MAX3488ECSA+ is a single-channel full-duplex transceiver that runs on a 3V to 3.6V rail. That 3.3V-only supply is the first thing to check against your bus. Data rate is 250 kbps. The 50 mV receiver hysteresis helps reject noise on long cable runs without external filtering.
Temp grade, package, and the 8-pin SOIC footprint
Not rated for engine bays, solar inverters, or outdoor telecom cabinets. The 8-SOIC narrow-body package is a common footprint; the 0.154-inch width matches industry-standard SOIC-8 land patterns. The 1/1 driver/receiver count means one differential pair in each direction — true full-duplex.
Active production — no obsolescence watch needed
Lifecycle status is Active. No EOL notice, no last-time-buy window. The ROHS3 compliance keeps it viable for EU and RoHS-restricted markets without exemption tracking. No stock-holding claim here — we source to order against an RFQ.
