CXAS4234Q

CXAS4234Q是一款高性能的四极单刀双掷（SPTT）模拟开关，在3.0V VCC下具有0.5Ω（典型）的超低Ron。CXAS4234Q在2.3V至4.5V的宽VCC范围内工作，专为通电前断开而设计。选择输入与TTL级兼容。
CXAS4234Q还配有智能电路，即使控制电压低于VCC电源电压，也能将VCC泄漏电流降至最低。此功能适合移动手机应用，允许直接与基带处理器通用IO接口，耗电量最小。也就是说，在实际应用中不需要额外的设备来改变控制水平，使之与VCC相同。
CXAS4234Q有QFN1.8x2.6-16L包装。标准产品是无铅和无卤素的。

电源电压：2.3~4.5V
•超低导通电阻：0.5欧
•3dB带宽：40MHz
铁路至铁路信号范围
合闸前断开
扩展控制输入范围内的低静态电流

产品简介

The CXAS4234Q is a high performance, quad, Single Pole Double Throw (SPDT) analog switch that features ultra-low Ron of 0.5 Ω (typical) at 3.0V VCC. The CXAS4234Q operates over a wide VCC range of 2.3V to 4.5V and is designed for break-before-make operation. The select input is TTL-level compatible.

CXAS4234Q is also featured with smart circuitry to minimize VCC leakage current even when the control voltage is lower than VCC supply voltage. This feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose IO with minimal battery consumption. In other word, there is no need of additional device to shift control level to be the same as that of VCC in real application.

The CXAS4234Q is available in QFN1.8x2.6-16L package. Standard Products are Pb-free and halogen-free.
