DG441B, DG442B Vishay Siliconix Improved Quad SPST CMOS Analog Switches DESCRIPTION The DG441B, DG442B are monolithic quad analog switches designed to provide high speed, low error switching of analog and audio signals. The DG441B, DG442B are upgrades to the original DG441, DG442. bing low on-resistance (45 , typ.) with high speed (tON 120 ns, typ.), the DG441B, DG442B are ideally suited for Data Acquisition, munication Systems, Automatic Test Equipment, or Medical Instrumentation. Charge injection has been minimized on the drain for use in sample-and-hold circuits. The DG441B, DG442B are 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.
