   产品概述 返回TOPR2B嘉泰姆

The CXAS42208 is a 6-bit 1-of-2 Mux/Demux designed to operate from 2.0V to 5.0V. This device can handle both digital and analog signals, and signals up to V_CC can be transmitted in either direction. The CXAS42208 has two control pins, each controlling three 1-of-2 muxes at the same time, and an enable pin that is used to put all outputs in high-impedance mode. The control pins are compatible with 1.8V logic thresholds and are backward compatible with 2.5V and 3.3V logic thresholds as well.

The CXAS42208 allows any SD, SDIO, and multimedia card host controllers to be expanded out to multiple cards or peripherals since the SDIO interface consists of 6-bits: CMD, CLK, and Data [0:3] signals. The CXAS42208 has two control pins that give additional flexibility to the user. For example, the ability to mux two different audio-video signals in equipment such as an LCD television, an LCD monitor, or a notebook docking station.R2B嘉泰姆

The CXAS42208 is available in Green TSSOP-24 and TQFN-4×4-24L packages. It operates over an ambient temperature range of -40℃ to+85℃.R2B嘉泰姆
