DG442LAK

Overview

The DG442LAK 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 an on-resistance of 17 Ω, turn-on time of 20 ns, and turn-off time of 12 ns. It provides 2000 V ESD protection and operates within a temperature range of -55 °C to +125 °C in a 16-pin CerDIP package.

Feature Summary

• Low voltage operation with BiCMOS wafer fabrication technology
• Fast switching action with minimal insertion loss
• TTL and CMOS compatible digital inputs
• Break-before-make switching logic

Applications

• Precision automatic test equipment
• Audio and video signal routing
• DSL and DSLAM systems
• Battery powered systems

Procurement Notes

Verify the specific suffix 'AK' corresponds to the 16-pin CerDIP package and the -55 °C to +125 °C operating temperature range as defined in the ordering information table. Confirm RoHS compliance status for the specific manufacturing lot, noting that older non-hermetic variants may differ from current specifications.

Selection Notes

Select the DG442LAK when complementary control logic to the DG441L is required, as it utilizes opposite control logic states. Ensure the application requires the specific -55 °C to +125 °C industrial temperature range and the mechanical robustness provided by the ceramic DIP package compared to plastic alternatives.

Part Context

The DG442LAK belongs to the DG441L/DG442L family of low-voltage analog switches. These devices are designed as pin-for-pin compatible companion units, differing primarily in their digital input logic polarity. The AK suffix specifically denotes the hermetic 16-pin Ceramic Dual In-Line Package (CerDIP) variant intended for high-reliability applications.
