Frequently asked questions
Does the MAX3088EESA+T support RS-422 full duplex?
No, the MAX3088EESA+T is a half-duplex transceiver. It uses a single pair of wires for both transmit and receive, so it cannot drive an RS-422 full-duplex bus that requires separate transmit and receive pairs. For full-duplex RS-422, look at a dual-channel transceiver like the MAX3082.
What is the closest pin-compatible alternative to the MAX3088EESA+T?
A direct pin-compatible alternative within the same family is the MAX3088EESA+ (non-tape-and-reel variant), which shares the same die and electrical specs. For a different data rate, the MAX3485EESA+ (12 Mbps, 3.3 V supply) is footprint-compatible but requires a 3.3 V rail.
