DG442DJZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DJZ is a quad single-pole single-throw (SPST) analog switch manufactured by Intersil, now part of Renesas Electronics. It operates with a single supply voltage ranging from 5V to 34V or dual supplies from ±5V to ±17V. The device features a maximum on-resistance of 85 ohms and offers low charge injection of -1pC. Switching times are specified at a maximum of 250ns for turn-on and 210ns for turn-off. It is housed in a 16-pin PDIP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin as Intersil or its successor entity Renesas Electronics. Confirm the specific suffix indicates the plastic DIP-16 package variant. Check RoHS compliance status against current regulatory requirements. Ensure the component matches the exact pinout and electrical specifications required for the target design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required for analog signal paths. Consider the 85-ohm on-resistance limit for signal integrity constraints. Evaluate the ±5V to ±17V dual supply range against available system power rails. Verify that the 16-pin PDIP form factor fits the mechanical layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG44x series of high-speed analog switches. It shares functional similarities with the DG441 and DG442 variants, differing primarily in packaging and specific electrical tolerances. The series is designed for general-purpose analog switching applications requiring low distortion and fast switching speeds.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Potential substitutes include the DG442BDJ-E3 and DG442DJ-E3. Verify pin compatibility and electrical parameter alignment before substitution. Note that some variants may be marked as not recommended for new designs.
