The MAX3087ECSA+ is a full-duplex transceiver for RS-422 and RS-485 protocols. It operates at 10 Mbps with 100 mV receiver hysteresis.
Housed in an 8-pin SOIC (0.154" body width, 3.90 mm), the MAX3087ECSA+ uses the industry-standard SOIC-8 land pattern.
Listed as Active on the lifecycle record, the MAX3087ECSA+ carries no last-time-buy risk and remains available for new designs.
The MAX3087 is a full-duplex transceiver (separate driver and receiver enable pins), while the MAX3082 is a half-duplex transceiver (shared driver/receiver enable). Both operate at 10 Mbps and share the same 8-SOIC footprint, so the choice depends on whether your bus requires four wires (full duplex) or two wires (half duplex).
Yes, the transceiver operates on a 5V supply and its logic inputs and outputs are 5V-tolerant, so it interfaces directly with 5V UARTs, MCUs, and FPGAs without level shifting.
Within the same family, the MAX3087ECSA+ is the commercial-temperature variant. The industrial-temperature version (MAX3087ECPA+, -40°C to +85°C) is pin-compatible and shares the same 8-pin DIP footprint, but the package differs (DIP vs SOIC). For a drop-in SOIC-8 replacement with extended temperature, the MAX3087EESA+ (extended industrial, -40°C to +85°C) is a direct alternative.
