MAX1480ACPI
nadajnik/odbiornik RS485/422 , DC=1023
The MAX1480A/MAX1480B/MAX1480C/MAX1490A/MAX1490B are complete, electrically isolated, RS-485/RS-422 data-communications interface solutions in ahybrid microcircuit. Transceivers, optocouplers, and atransformer provide a complete interface in a standardDIP 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, allowingerror-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. TheMAX1480A/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 protectedagainst excessive power dissipation by thermal shut-down circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safefeature that guarantees a known output ROlow for theMAX1480A/B/C, RO high for the MAX1490A/B/C if theinput is open circuit.The MAX1480A/MAX1480B/MAX1480C/MAX1490A/MAX1490B typically withstand 1600VRMS 1 minute or2000VRMS 1 second . Their isolated outputs meet allRS-485/RS-422 specifications. The MAX1480A/B/C areavailable in a 28-pin DIP package, and the MAX1490A/Bare available in a 24-pin DIP package Dokumentacja: http://www.wolumen53.com/pdf/MAX1480.pdf
