全新 原装 现货 热卖 MAX1480BEPI

General DescriptionThe 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 powersboth sides of the interface.The MAX1480B/MAX1480C/MAX1490B feature reducedslew-ratedrivers that minimize EMI and reduce reflectionscaused 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 communication,while the MAX1490A/B feature full-duplex communication.Drivers are short-circuit current limited and protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a highimpedancestate. The receiver input has a fail-safefeature that guarantees a known output (RO low 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.
