MAX485ECSA Datasheet

RS-422/RS-485 Interface IC


The MAX481E, MAX483E, MAX485ECSA , MAX487E–MAX491E,and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E,MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485ECSA+, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps. MAX485ECSA Features • -7V to +12V Common-Mode Input Voltage Range• Three-State Outputs• 30ns Propagation Delays, 5ns Skew (MAX481E/485E/490E/491E/1487E)• Full-Duplex and Half-Duplex Versions Available• Allows up to 128 Transceivers on the Bus (MAX487E/MAX1487E)• Current Limiting and Thermal Shutdown for Driver Overload Protection MAX485ECSA Applications • Low-Power RS-485 Transceivers• Low-Power RS-422 Transceivers• Level Translators• Transceivers for EMI-Sensitive Applications• Industrial-Control Local Area Networks
