Analog Switch Quad SPST 16-Pin PDIP

The DG445B is monolithic quad analog switches designed to provide high speed, low error switching of analog and audio signals. The DG445B is upgrades to the original DG444, DG445.Combing low on-resistance (45 O, typ.) with high speed (tON 120 ns, typ.), the DG445B is ideally suited for Data Acquisition, Communication Systems, Automatic Test Equipment, or Medical Instrumentation. Charge injection has been minimized on the drain for use in sample-and-hold circuits.The DG445B is built using Vishay Siliconix’s high-voltage silicon-gate process. An epitaxial layer prevents latchup.When on, each switch conducts equally well in both directions and blocks input voltages to the supply levels when off.
