DG444B, DG445B Vishay Siliconix Improved Quad SPST CMOS Analog Switches DESCRIPTION FEATURES The DG444B, DG445B are monolithic quad analog switches designed to provide high speed, low error switching of analog and audio signals. The DG444B, DG445B are upgrades to the original DG444, DG445. Combing low on-resistance (45 , typ.) with high speed (tON 120 ns, typ.), the DG444B, DG445B 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 DG444B, DG445B 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. • Halogen-free according to IEC 61249-2-21 Definition • Low On-Resistance: 45 W • Low Power Consumption: 1 mW • Fast Switching Action - tON: 120 ns • Low Charge Injection • TTL/CMOS-Compatible Logic • Compliant to RoHS Directive 2002/95/EC BENEFITS • • • • • Low Signal Errors and Distortion Reduced Power Supply Consumption 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 DG444B Dual-In-Line and SOIC IN1 1 16 IN2 D1 2 15 D2 Logic DG444B DG445B S1 3 14 S2 0 ON OFF V- 4 13 V+ 1 OFF ON GND 5 12 VL S4 6 11 S3 D4 7 10 D3 IN4 8 9 IN3 TRUTH TABLE Logic "0" 0.8 V Logic "1" 2.4 V Top View DG444B QFN16 (4 x 4 mm) ORDERING INFORMATION D1 IN1 IN2 D2 16 15 14 Temp Range 13 S1 1 12 S2 V- 2 11 V+ GND 3 10 VL S4 4 9 S3 5 6 7 Document Number: 72626 S11-1350-Rev.
