The ADM3082/ADM3085/ADM3088 are high-speed RS-485/RS-422 transceivers consisting of one driver and one receiver per package. The devices feature fail-safe operation, ensuring a logic-high receiver output when the receiver in-puts are open-circuit or short-circuit. This guarantees that the receiver output will be high if all the transmitters on a terminated bus are disabled (high-impedance). The ADM3082 has a slew rate limited driver to minimize electromagnetic interference (EMI) and reduce reflections caused by incorrectly terminated cables. This allows for error-free transmission at data rates up to 115kbps. The ADM3085 offers a higher slew rate allowing data rates up to 500kbps, while the ADM3088 has a driver whose slew rate is not limited, allowing data rates of up to 10Mbps. All devices in the family feature ±15kV electrostatic discharge (ESD) protection and high receiver input impedance (1/8 unit load), allowing up to 256 transceivers on the bus. The devices have low current drain of 375µA un-loaded, or fully loaded with the drivers disabled, and feature an ultra-low power (1nA) shutdown mode. * EMI-SensitiveSystems * Enhanced Replacement for Industry-Standard Parts
