CXAS42217是一种32位高速、1.8V CMOS逻辑兼容的2:1多路复用/解复用总线交换机。开关的低导通电阻允许输入连接到输出，而不增加传播延迟或产生额外的地面反弹噪声。
该装置可用于需要切换两条总线的应用中。CXAS42217可以用作32位多路复用器或解复用器。
两个I/O（EN，S）输入提供芯片启用和多路复用器选择控制。
CXAS42217设计用于在切换总线时防止总线B和总线C之间的通电。
•两个端口之间的11Ω开关连接
•通过交换机的最小传播延迟
•“T”型开关结构，减少串扰
加强和之间的隔离
未选择的B或C总线
•低静态电源电流
•与1.8V逻辑兼容的控制输入

产品概述 返回TOP
The device can be used in applications where two buses need to be switched. The CXAS42217 can be used as a 32-bit multiplexer or demultiplexer.
Two I/O (EN, S) inputs provide chip enable and multiplexer select control.
The CXAS42217 is designed to prevent through-current between bus B and bus C when switching buses.
The CXAS42217 is available in Green LQFP-14×14-100L package. It operates over an ambient temperature range of -40℃ to +85℃.
