Isolated RS485/RS422 data interfaces

7 November 2001 Telecoms, Datacoms, Wireless, IoT

The MAX1480EA/MAX1480EC/MAX1490EA/MAX1490EB are complete, electrically isolated, RS485/RS422 data communications interface solutions in hybrid microcircuit available from Maxim. The RS485/RS422 I/O pins are protected against ±15 kV electrostatic discharge (ESD) shocks, without latchup. Transceivers, optocouplers, and a transformer provide a complete interface in a standard DIP package. A single +5 V supply on the logic side powers both sides of the interface.

The MAX1480EC/MAX1490EB feature reduced-slew-rate drivers that minimise EMI and reduce reflections caused by improperly terminated cables, allowing errorfree data transmission at data rates up to 160 Kbps. The MAX1480EA/MAX1490EA driver slew rate is not limited, allowing transmission rates up to 2,5 Mbps. The MAX1480EA/MAX1480EC are designed for half-duplex communication, while the MAX1490EA/MAX1490EB feature full-duplex communication.

The MAX1480EA/MAX1480EC are available in 28-pin DIP package, and the MAX1490EA/MAX1490EB in 24-pin DIP package.
