UMDM27518数据手册UTC中文资料规格书

描述 Description

The UTC UMDM27518 is a 6-bit 1-of-2 high-speed multiplexer/demultiplexer operating from 1.65V to 3.6V. Both digital and analogsignals can be handled, and signals up to V+ can be transmitted ineither direction.The UTC UMDM27518 has two control pins working separately,each controlling three 1-of-2 multiplexers at the same time. Oneenable pin is used to put all outputs in high-impedance mode. Thecontrol pins are compatible with 1.8V logic thresholds and arebackward compatible with 2.5V and 3.3V logic thresholds as well.The UTC UMDM27518 allows any SD, SDIO, and multimedia cardhost controllers to be expanded out to multiple cards or peripheralssince the SDIO interface consists of 6-bits: CMD, CLK, and Data [0:3]signals. The UTC UMDM27518 has two control pins that giveadditional flexibility to the user. For example, the ability to mux twodifferent audio-video signals in equipment such as an LCD television,an LCD monitor, or a notebook docking station.
