DG441LAK

Overview

The DG441LAK is a precision monolithic quad SPST low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±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 supports TTL and CMOS logic inputs with low leakage current of 0.25 nA and 2000 V ESD protection. The component is housed in a 16-pin CerDIP package and functions as a normally closed switch.

Feature Summary

Low voltage operation compatible with single and dual power supplies
Fast switching speeds with minimal insertion loss
TTL and CMOS logic input compatibility
Break-before-make switching action for signal integrity

Applications

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

Procurement Notes

Verify the specific suffix 'AK' corresponds to the 16-pin CerDIP package and -55 °C to +125 °C temperature range. Confirm RoHS compliance status as older manufacturing runs may differ. Validate pinout alignment with legacy designs requiring this specific ceramic DIP footprint.

Selection Notes

Select this part for applications requiring normally closed (NC) configuration among the DG441/442 family. Ensure supply voltages remain within the specified 2.7 V to 12 V single or ±3 V to ±6 V dual ranges. Consider the 17 Ω on-resistance for signal path losses in high-precision circuits.

Part Context

The DG441LAK belongs to the DG441L/DG442L series, which are companion devices offering improved performance over standard industry equivalents. While the DG441LAK provides four normally closed switches, its counterpart DG442LAK offers four normally open switches within the same package and specification envelope.
