DG271BDY [Siliconix]

The DG271B is a high-speed quad single-pole single-throw analog switch built on Vishay Siliconix's proprietary high voltage silicon gate process. It features low on-resistance (32 Ω typical), low charge injection (5 pC), and fast switching times (55 ns). Each switch conducts equally well in both directions when on and blocks up to the supply voltage when off. An epitaxial layer prevents latchup. The device includes a redesigned internal regulator for improved start-up performance. It is TTL/CMOS compatible and available in Pb-free/RoHS compliant versions.
