FEATURES  
GENERAL DESCRIPTION  
Enhanced Slew Rate Limiting for Error-Free Data  
Transmission  
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).  
Fail-Safe Receiver Operation while Maintaining  
EIA/TIA-485 compatibility  
Low-Current (1nA) Shutdown Mode  
High Input Impedance — Up to 256 Transceivers on Bus  
15ꢀk ESD ꢁrotection (Human Body Model) on  
RS-485 I/O pins  
The ADM3082 has a slew-rate limited driver to minimize  
electromagnetic interference (EMI) and reduce reflections  
caused by incorrectly terminated cables. This allows error-  
free transmission at data rates up to 115kbps.  
ꢁin-Compatible with Industry Standard 75176  
AꢁꢁLICATIONS  
Enhanced Replacement for Industry-Standard ꢁarts  
EMI-SensitiveSystems  
Level Translation  
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.  
All devices in the family feature 15kꢀ electrostatic dis-  
charge (ESD) protection and high receiver input imped-  
ance (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 fea-  
ture an ultra-low power (1nA) shutdown mode.
