DG441DJZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441DJZ is a monolithic quad single-pole single-throw (SPST) normally-closed CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent switches in a 16-pin plastic dual in-line package (PDIP). The device operates with a single supply voltage ranging from +5V to +34V or split supplies from ±5V to ±22V. Key electrical specifications include a maximum on-resistance of 85 ohms, a maximum on-time of 250ns, and an off-time of 120ns. Charge injection is specified at -1pC, with leakage current not exceeding 500pA. The component supports an operating temperature range of -40°C to +85°C and is RoHS compliant.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST normally-closed analog switches within a single monolithic CMOS structure.
• Features TTL and CMOS compatible digital inputs for straightforward logic interfacing.
• Provides low power consumption suitable for battery-operated or energy-efficient applications.
• Includes an epitaxial layer to prevent latch-up issues associated with older CMOS technologies.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring signal routing and multiplexing.
• Sample and hold circuits utilizing the low charge injection characteristics.
• Industrial process control loops involving analog signal switching.
• Communications equipment for signal path configuration.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Check for end-of-life notifications and production discontinuation notices from Renesas. Ensure replacement components meet identical pinout and electrical specifications if sourcing alternatives is necessary for existing designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed SPST configuration is required rather than the more common normally-open type. Confirm that the 85-ohm on-resistance meets the signal integrity requirements of the application. Verify that the 16-PDIP package fits the available board space and manufacturing capabilities compared to surface-mount alternatives like the DG441DYZ-T.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG441DJZ belongs to the DG441 series of monolithic CMOS analog switches. This series is designed as a drop-in replacement for legacy devices, offering improved performance metrics such as lower on-resistance and faster switching speeds compared to earlier generations. The 'DJZ' suffix specifically denotes the 16-pin PDIP package variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include DG441DYZ-T and DG441DVZ. These alternatives offer the same functional specifications but utilize different packaging formats, specifically SOIC-Narrow and TSSOP respectively, which may require PCB layout modifications.
