DG442DJ+

Overview

The DG442DJ+ is a quad, single-pole/single-throw (SPST) analog switch fabricated using a silicon-gate process. It features four normally open switches with an on-resistance of 85 ohms maximum and an on-resistance match of 4 ohms maximum between channels. The device operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include a turn-on time of 250 nanoseconds maximum, a turn-off time of 170 nanoseconds maximum, and charge injection of 10 picocoulombs maximum. It supports rail-to-rail signal handling and maintains off-leakage current below 5nA at +85°C.

Feature Summary

Improved on-resistance matching between channels for balanced signal routing
Guaranteed on-resistance flatness over the entire signal range
Low power consumption suitable for battery-operated systems
High electrostatic discharge tolerance per Method 3015.7

Applications

Sample-and-hold circuits
Audio-signal routing
Test equipment
Communication systems

Procurement Notes

Verify the ordering suffix 'DJ+' corresponds to the Plastic DIP package and the -40°C to +85°C temperature range. Confirm lead-free status via the '+' designation. Check datasheet revision history for updates on ruggedized plastic specifications. Ensure compatibility with existing PCB footprints for 16-pin packages.

Selection Notes

Select this component when four independent SPST switches are required in a single package. The DG442 variant provides normally open logic, distinct from the DG441's normally closed configuration. Consider the bipolar supply operation requirements for optimal on-resistance flatness and channel matching performance.

Part Context

This part belongs to the DG441/DG442 family of improved analog switches. It serves as a direct upgrade to industry-standard predecessors, offering enhanced electrical characteristics such as lower charge injection and better on-resistance matching while maintaining pin compatibility.
