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 75176 APPLICATIONS
Enhanced Replacement for Industry-Standard Parts EMI-Sensitive Systems Level Translation LANs for Industrial Control APPLICATIONS
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). 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.
