SP485E：增强型低电磁干扰（EMI）半双工RS-485收发器
The SP481E and SP485E are a family of half-duplex transceivers that meet
the specifications of RS-485 and RS-422 serial protocols with enhanced
ESD performance. The ESD tolerance has been improved on these devices to
over +15kV for both Human Body Model and IEC1000-4-2 Air Discharge
Method. These devices are pin-to-pin compatible with Exar's SP481 and
SP485 devices as well as popular industry standards. As with the
original versions, the SP481E and SP485E feature Exar's BiCMOS design
allowing low power operation without sacrificing performance. The SP481E
and SP485E meet the requirements of the RS-485 and RS-422 protocols up
to 10Mbps under load. The SP481E is equipped with a low power shutdown
mode.
