1 DG27 High-Speed Quad Monolithic SPST CMOS Analog Features Benefits Applications Fast ing : ns Low Charge Injection: pc Low r DS(on) : 32 TTL/CMOS Compatible Low Leakage: pa Description Fast Settling Times Reduced ing Glitches High Precision High Speed ing Sample/Hold Digital Filters Op Amp Gain ing Flight Control Systems Automatic Test Equipment Choppers Communication Systems The DG27 high speed quad single-pole single-throw analog switch is intended for applications that require low on-resistance, low leakage currents, and fast switching speeds. Built on proprietary high voltage silicon gate process to achieve superior on/off performance, each switch conducts equally well in both directions when on, and blocks up to the supply voltage when off. An epitaxial layer prevents latchup.
