Description: The MAX481E, MAX483E, MAX485E, 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, MAX485E, MAX490E, MAX491E, and MAX1487E
are not limited, allowing them to transmit up to 2.5Mbps.-The MAX481E, MAX483E, MAX485E, MAX487E-MAX491E, and MAX1487E are low-power transceivers for RS-485 andRS-422 communications in harsh environments.

Description: RS-232、RS-422与RS-485都是串行数据接口标准，最初都是由电子工业协会（EIA）制
订并发布的，RS-232在1962年发布，命名为EIA-232-E，作为工业标准，以保证不同厂家产品
之间的兼容。RS-422由RS-232发展而来，它是为弥补RS-232之不足而提出的。为改进RS-232
通信距离短、速率低的缺点，RS-422定义了一种平衡通信接口，将传输速率提高到10Mb/s，
传输距离延长到4000英尺（速率低于100kb/s时），并允许在一条平衡总线上连接最多10个接
收器-RS-232, RS-422 and RS-485 serial data interface standards are the first by the Electronics Industry Association (EIA) and published in, RS-232 issued in 1962, named for the EIA-232-E, as the industry standard to ensure that different manufacturers of compatible products. RS-422 by the development of RS-232, which is designed to remedy the lack of RS-232 made. RS-232 to improve the short-distance communications, the shortcomings of low-rate, RS-422 defines a balance between communication interface transfer rate up to 10Mb/s, transmission distance was extended to 4000 feet (at rates of less than 100kb/s), the and allow the balance on a bus to connect up to 10 receivers
