DG417LAK

DG417LAK Description

The DG417LAK is a single-pole single-throw (SPST) analog switch designed for high-performance applications requiring low on-state resistance and minimal charge injection. Manufactured by Vishay Siliconix, this obsolete component is housed in an 8-pin CERDIP package, making it suitable for through-hole mounting. With a supply voltage range of ±3V to ±6V for dual supplies and 2.7V to 12V for single supplies, the DG417LAK offers flexibility in power requirements. Its low leakage current of 1nA and channel capacitance of 5pF ensure minimal signal degradation, while its maximum on-state resistance of 20 ohms provides efficient signal transmission. The switch time of 43ns for turn-on and 31ns for turn-off ensures rapid switching capabilities. The DG417LAK is REACH unaffected and has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited storage conditions.
