产品简介

CXAS42161是一种高性能、双、单刀双掷（SPDT）CMOS模拟开关，用于交换USB 2.0全速信号。高带宽和低导通电阻使该开关能够以最小的信号失真通过USB低速和全速信号。
CXAS42161具有开关之间的电阻匹配保证（0.3Ω类型）和信号范围（1Ω类型）内的电阻平坦性保证。这确保了切换信号时的良好线性和低失真。该器件采用亚微米CMOS工艺制造，开关速度快，设计为通断后再通电。选择输入与TTL级兼容。
CXAS42161有绿色UTQFN-1.8×1.4-10L包装。它在-40℃到+85℃的环境温度范围内工作。
•工作电压：+1.8V至+4.3V
•导通电阻：6Ω（典型值）

   产品概述 返回TOP

The CXAS42161 is a high-performance, dual, single-pole/ double-throw (SPDT) CMOS analog switch designed for switching USB 2.0 full-speed signals. High bandwidth and low on-resistance make this switch able to pass both USB low- and full-speed signal with minimum signal distortion.

The CXAS42161 features guaranteed on-resistance matching (0.3Ω TYP) between switches and guaranteed on-resistance flatness over the signal range (1Ω TYP). This ensures excellent linearity and low distortion when switching signals.

The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and designed for break-before-make operation. The select input is TTL-level compatible.

CXAS42161 is available in Green UTQFN-1.8×1.4-10L package. It operates over an ambient temperature range of -40℃ to +85℃.
