ISL8483EIB集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

These Intersil RS-485, RS-422 devices are ESD protected, BiCMOS 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive devices, this Intersil family is specified for 10 tolerance supplies (4.5V to 5.5V).

The ISL8483E utilizes slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or un-terminated stubs in multidrop and multipoint applications.
