DG442B

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. Combing low on-resistance (45 , typ.) with high speed (tON 120 ns, typ.), the DG441B, DG442B are 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 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. FEATURES Low On-Resistance: 45  Low Power Consumption: 1 mW Fast Switching Action - tON: 120 ns Low Charge Injection - Q: - 1 pC TTL/CMOS-Compatible Logic Single Supply Capability Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 BENEFITS Less Signal Errors and Distortion Reduced Power Supply Requirements Faster Throughput Reduced Pedestal Errors Simple Interfacing APPLICATIONS Audio Switching Data Acquisition Sample-and-Hold Circuits Communication Systems Automatic Test Equipment Medical Instruments FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG441B Dual-In-Line and SOIC IN1 1 ...
