These IC’s are composed of an independent 2 channel multiplexer with common SELECT and ENABLE INPUT. s The AC257 is a non inverting multiplexer. When the ENABLE INPUT is held ”High”, outputs s of both IC’s become high impedance state. If SELECT INPUT is held ”Low”, ”A” data is DESCRIPTION selected, when SELECT INPUT is ”High”, ”B” The AC257 is an advanced high-speed CMOS www.DataSheet4U.com data is chosen. QUAD 2 CHANNEL MULTIPLEXER (3-STATE) All inputs and outputs are equipped with fabricated with sub-micron silicon gate and 2 protection circuits against static discharge, giving double-layer metal wiring C MOS technology. them 2KV ESD immunity and transient excess It is ideal for low power applications mantaining voltage.
