ADM3088数据手册ADI中文资料规格书

描述 Description

The ADM3082/ADM3085/ADM3088 are high-speedRS-485/RS-422 transceivers consisting of one driver and onereceiver per package. The devices feature fail-safe operation,ensuring a logic-high receiver output when the receiver in-putsare open-circuit or short-circuit. This guarantees thatthe receiver output will be high if all the transmitters on aterminated 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 onthe bus. The devices have low current drain of 375µA un-loaded,or fully loaded with the drivers disabled, and featurean ultra-low power (1nA) shutdown mode.
