DG442LDQ-T1-E3

Overview

The DG442LDQ-T1-E3 is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on a single supply of 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device features a typical on-resistance of 17 Ω, fast switching times with turn-on at 20 ns and turn-off at 12 ns, and ultra-low leakage current of 0.25 nA. It provides 2000 V ESD protection and is compatible with TTL and CMOS logic levels. Packaged in a 16-pin TSSOP, it supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

BiCMOS wafer fabrication technology enables operation on both single and dual power supplies.
Flat on-resistance over the analog signal range ensures minimal insertion loss and distortion.
Break-before-make switching action prevents signal glitches during channel transitions.
TTL and CMOS logic compatibility allows for simple interfacing with standard digital control circuits.

Applications

Precision automatic test equipment
Precision data acquisition systems
Communication systems
Battery powered systems
Audio and video signal routing

Procurement Notes

Verify the component against the official Vishay datasheet Document Number 71399 to confirm specifications. Ensure the ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status as per the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when low voltage operation between 2.7 V and 12 V is required. Choose this part for applications demanding high speed switching with minimal charge injection. Verify that the 16-pin TSSOP package fits the board layout constraints and that the thermal dissipation requirements are met within the specified operating temperature range.

Part Context

This device belongs to the DG441L/DG442L series of precision analog switches. It serves as a companion to the industry-standard DG441L/DG442L but offers improved performance characteristics through BiCMOS technology. The DG442 variant specifically utilizes opposite control logic compared to the DG441.
