Overview
The NLAS324USG is a dual SPST (Single Pole, Single Throw) analog switch produced by onsemi. This device is designed for low-voltage, single-supply applications and is available in an ultra-small 8-pin package. It utilizes advanced 0.6 μm CMOS technology, which significantly improves the on-resistance compared to older higher voltage technologies. The NLAS324USG allows for the independent selection of two analog or digital signals, making it versatile for various applications.
