Active RS422/RS485 full-duplex transceiver — 2.5 Mbps, 24-DIP
The MAX1490EAEPG+ is a single-channel full-duplex transceiver supporting RS422 and RS485 protocols at 2.5 Mbps, with one driver and one receiver in a 24-pin DIP package.
Receiver hysteresis and noise margin for long cable runs
The receiver includes 70 mV of hysteresis, which provides noise immunity on long twisted-pair cable runs common in RS422/RS485 networks. This hysteresis level helps reject differential noise picked up over distances where ground potential differences and cable capacitance degrade the signal edge.
Through-hole 24-PDIP package — board-fit and integration
Housed in a 24-DIP (0.600-inch, 15.24 mm) through-hole package, the MAX1490EAEPG+ mates with standard 0.100-inch pitch DIP sockets or can be soldered directly into plated through-holes. The 24-PDIP supplier package offers a robust mechanical connection for prototyping and low-volume production where rework or socketing is preferred over surface-mount assembly.
