• ESD Protection for RS- 485 iO Pins: 15kV Human Body Model, 15kV IEC61000- 4- 2 Air- Gap Discharge, 8kV IEC61000- 4- 2 Contact Discharge
• 5V Supply Voltage Range
• Enhanced Slew- Rate Limiting
• 1uA Low- Current Shutdown Mode
• • 7V to +12V Common- Mode Input Voltage Range
• Allows up to 256 Transceivers on the Bus
• Thermal Shutdown Current- Limiting for Driver Overload Protection
• Data transmission up to 2.5Mbps
• Slew- rate- limited driver which minimizes EMI and reduces reflections resulted from improperly terminated cables
• Enhanced electrostatic discharge (ESD) protection: All of the transmitter outputs and receiver inputs are protected to ±15kV using IEC61000- 4- 2 Air- Gap Discharge, ±15kV using the Human Body Model and ±8kV using IEC61000- 4- 2 Contact Discharge
• Drivers are short circuit current limited
• Fail- safe feature of the receiver input guarantees a logic- high output if both inputs are open, shorted or idle
• Power up/down mode, glitch- free driver outputs permit live insertion or removal of the transceiver into/from the data bus
• CMOS design offers significant power savings without sacrificing ruggedness against overload or ESD damage
• Typical quiescent current is only 300uA during operation and 1uA in shutdown mode
• Intended for half- duplex communication
• Available in SOP8 and DIP8 packages
