CXDS4224QA CXDS4224QB是一个双单刀双掷（SPTT）模拟开关，设计用于从一个电源（+2.3V到+5.5V）运行。该器件具有低的导通电阻和良好的导通电阻与通前断相匹配的特性，以防止信号从一个通道传输到另一个通道时的信号失真。该装置在断电模式下能真正隔离，VCC=0，信号管脚能承受高达8V的电压，当信号管脚的电压高于VCC时，回流到电源的电流很小。这些特性使得该设备适合于将基带与独立的音频驱动器（D或K级）以及信号可用后的通电等情况隔离。INx控制引脚具有过电压保护，允许高于VCC的电压在引脚上出现高达5.5V的电压，而不会损坏或中断部件的操作，无论工作电压如何。CXDS4224QA CXDS4224QB还配备了智能电路，即使INx控制电压低于VCC电源电压，也能将VCC泄漏电流降至最低。CXDS4224QA CXDS4224QB有QFN2116-10L和QFN1418-10L两种包装。标准产品无铅无卤。

产品概述 返回TOP
The CXDS4224QA CXDS4224QB is a dual single-pole double-throw (SPDT) analog switch that is designed to operate from a single power supply (+2.3V to +5.5V). The device offers low ON-state resistance and excellent ON-state resistance matching with break-before-make feature, to prevent signal distortion during the transferring of a signal from one channel to another. The device is capable of truly isolation in power-down mode, VCC=0 and signal pins are able to withstand voltage up to 8V. As signal pins’ voltage is higher than VCC, very little current will flow back to the supply. These features make this device suitable for isolating Base-Band from independent audio drivers, Class D or K and such circumstance as power-up after signals are being available.
The INx control pin has overvoltage protection that allows voltages above VCC, up to 5.5V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage. The CXDS4224QA CXDS4224QB is also featured with smart circuitry to minimize VCC leakage current even when INx control voltage is lower than VCC supply voltage.
The CXDS4224QA CXDS4224QB is available in QFN2116-10L and QFN1418-10L package. Standard product is Pb-Free and halogen-Free.
