CXDS4219B是一种高性能、单刀双掷（SPTT）CMOS模拟开关，用于总线交换或音频交换应用。它具有高带宽高达400兆赫在-3分贝和低导通电阻（5.5Ω典型）。SEL引脚具有过电压保护，允许电压高于VCC，引脚上存在高达7.0V的电压，而不会损坏或中断部件的运行，无论工作电压如何。
CXDS4219B还具有智能电路，即使当SEL控制电压低于VCC电源电压时，也能将VCC泄漏电流降至最低。换言之，在实际应用中，不需要额外的器件来改变SEL电平，使之与VCC的相同。CXDS4219B有标准SOT-363（SC-70-6L）组件。标准产品无铅无卤。

一.产品概述
The CXDS4219B is a high performance, single pole double throw (SPDT) CMOS analog switch for bus switching or audio switching applications. It features high bandwidth up to 400MHz at -3dB and low on-resistance (5.5Ω Typ.). The SEL pin has overvoltage protection that allows voltages above VCC, up to 7.0V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage.
The CXDS4219B is also featured with smart circuitry to minimize VCC leakage current even when SEL control voltage is lower than VCC supply voltage. In other word, there is no need of additional device to shift SEL level to be the same as that of VCC in real application.
The CXDS4219B is available in standard SOT-363(SC-70-6L) package. Standard product is Pb-Free and halogen-Free.
