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 CXAS42217 is a 32-bit high speed, 1.8V CMOS logic compatible 2:1 multiplexer/demultiplexer bus switch. The low on-resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
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℃.
