... RS-422 standards for balanced communication. Unlike competitive devices, this Intersil family is specified for 10% tolerance supplies (4.5V to 5.5V). The ISL8483, ISL8488, and ISL8489 utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. ...

... When testing the ISL8483, the RE signal high time must be short enough (typically <200ns) to prevent the device from entering SHDN. 7. The ISL8483 is put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See “ ...

... EMI. Drivers of the ISL8483/85/89/91 are three-statable via the active high DE input. The ISL8483/88/89 driver outputs are slew rate limited to minimize EMI, and to minimize reflections in unterminated or improperly terminated networks. Data rate on these slew rate limited versions is a maximum of 250kbps. Outputs of ISL8485/90/91 drivers are not limited, so faster output transition times allow data rates of at least 5Mbps ...

... Disabling both the driver and the receiver for less than 50ns guarantees that the ISL8483 will not enter shutdown. Note that receiver and driver enable times increase when the ISL8483 enables from shutdown. Refer to Notes 5-8, at the end of the Electrical Specification table, for more information. o ...
