Description

RS422/RS485 TXRX 250KBPS 5.5V DIP-24
The MAX1480A/MAX1480B/MAX1480C/MAX1490A/ MAX1490B are complete, electrically isolated, RS-485/ RS-422 data-communications interface solutions in a hybrid microcircuit. Transceivers, optocouplers, and a transformer provide a complete interface in a standard DIP package. A single +5V supply on the logic side pow- ers both sides of the interface. The MAX1480B/MAX1480C/MAX1490B feature reduced- slew-rate drivers that minimize EMI and reduce reflec- tions caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. The MAX1480A/MAX1490A driver slew rate is not limited, allowing transmission rates up to 2.5Mbps. The MAX1480A/B/C are designed for half-duplex communi- cation, while the MAX1490A/B feature full-duplex com- munication. Drivers are short-circuit current limited and protected against excessive power dissipation by thermal shut- down circuitry that places the driver outputs into a high- impedance state. The receiver input has a fail-safe feature that guarantees a known output (RO low for the MAX1480A/B/C, RO high for the MAX1490A/B) if the input is open circuit. The MAX1480A/MAX1480B/MAX1480C/MAX1490A/ MAX1490B typically withstand 1600VRMS (1 minute) or 2000VRMS (1 second). Their isolated outputs meet all RS-485/RS-422 specifications. The MAX1480A/B/C are available in a 28-pin DIP package, and the MAX1490A/B are available in a 24-pin DIP package.
