一.产品概述
The CXAS4230QB is a high performance, dual Single Pole Double Throw (SPDT) analog switch with negative swing audio capability that features ultra-low Ron of 0.75Ω (typical) at 3.6V VCC. The CXAS4230QB operates over a wide VCC range of 2.3V to 5.5V and is designed for break-before-make operation. The select input is TTL-level compatible.
CXAS4230QB 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 CXAS4230QB is available in QFN1418-10L package. Standard product is Pb-Free and halogen-Free.
