ISL83485IBZ-T集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

3.3V, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers

These Intersil RS-485/RS-422 devices are BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Unlike competitive devices, this Intersil family is specified for 10 tolerance supplies (3V to 3.6V).

The ISL83483 and ISL83488 utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications.
