ISL81487EIPZ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, fractional unit load (UL), 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).
