描述
TMUX1574是一款互补金属氧化物半导体(CMOS)开关.TMUX1574提供具有4个通道的2:1 SPDT开关配置.1.5V至5.5 V的宽运行电源电压范围使其可用于从服务器和通信设备到工业应用的各种应用的需求。该器件可在源极(SxA,SxB)和漏极(Dx)引脚上支持双向模拟和数字信号,并且可以传递高于电源的信号(高达V DD x 2),最大值为5.5V。
TMUX1574的信号路径上高达3.6V的关断保护可在移除电源电压(V DD = 0V)时提供隔离。如果没有该保护功能,开关可通过内部ESD二极管为电源轨进行反向供电,从而对系统造成潜在损坏。
失效防护逻辑电路允许在施加电源引脚上的电压之前,先施加逻辑控制引脚上的电压,从而保护器件免受潜在的损害。所有控制输入都具有兼容1.8V逻辑的阈值,当器件在有效电源电压范围内运时,这些阈值可确保TTL和CMOS逻辑兼容性。
