Analog Devices ADM3085
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 up to 10Mbps. The devices have low current drain of 375µA unloaded, or fully loaded with the drivers disabled, and feature an ultra-low power (1nA) shutdown mode.| Part No. | ADM3085 |

GENERAL DESCRIPTION
FEATURES
Enhanced Slew Rate Limiting for Error-Free Data Transmission Fail-Safe Receiver Operation while Maintaining EIA/TIA-485 compatibility High Input Impedance — Up to 256 Transceivers on Bus ±15kV ESD Protection (Human Body Model) on RS-485 I/O pins Pin-Compatible with Industry Standard 75176APPLICATIONS
Enhanced Replacement for Industry-Standard Parts EMI-Sensitive Systems Level Translation LANs for Industrial ControlAPPLICATIONS
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 inputs 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.
