DG604EEQ-T1-GE4

Overview

The DG604EEQ-T1-GE4 is a CMOS analog multiplexer manufactured by Vishay Siliconix, housed in a 14-pin TSSOP package. It features four independent channels that route one of four inputs to a common output based on 3-bit binary address lines (A0, A1, and EN). The device operates from a single supply of +3 V to +16 V or dual supplies of ±3 V to ±8 V. Key electrical specifications include an ultralow charge injection of less than ±0.4 pC, typical leakage currents of 16 pA at 25 °C, and a typical on-resistance of 64 Ω. It supports a bandwidth of 414 MHz and functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Ultra-low charge injection ensures minimal signal distortion during switching operations.
• Low leakage current characteristics maintain signal integrity across the full analog voltage range.
• Break-before-make switching action prevents momentary short circuits between channels.
• CMOS construction allows for low power consumption and compatibility with standard logic levels.

Applications

• Data acquisition systems
• Medical instruments
• Precision instruments
• Communications systems
• Automated test equipment
