What this part is and where it lands on the bus
The MAX3087EESA+ is a single RS-422/RS-485 transceiver in an 8-SOIC package. It handles one driver and one receiver in a full-duplex configuration, pushing data at 10 Mbps over twisted-pair cabling.
Full duplex at 10 Mbps — what that means for the link
Full duplex means the driver and receiver operate simultaneously on separate wire pairs, so the bus can transmit and receive at the same time. The 10 Mbps data rate is the maximum; actual throughput depends on cable length, termination, and the number of nodes.
Sourcing and lifecycle — no LTB pressure here
There is no last-time-buy notice, no NRND flag, and no indication of phase-out. That means it can be specified into new designs without worrying about a sudden EOL. The ROHS3 compliance is current.
Package and footprint — 8-SOIC, surface-mount
The MAX3087EESA+ comes in an 8-SOIC package with a 3.90 mm body width (0.154"). It is surface-mount only — no through-hole variant in this suffix. The supplier device package is also 8-SOIC, so the marking on the part matches the footprint. The tube shipping medium is typical for this package; if you need tape-and-reel for automated assembly, check the suffix — the EESA+ is tube, not reel.
