DG412DYZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412DYZ is a monolithic quad SPST CMOS analog switch manufactured by Renesas Electronics. It features four independent switches with a maximum on-resistance of 35 Ohms and a supply voltage range of 5V to 44V single or ±5V to ±20V dual. The device operates within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum turn-on time of 175ns, a maximum turn-off time of 145ns, and a maximum power supply current of 1µA. It supports a DC switch current of 30mA and is housed in a 16-lead SOIC-Narrow package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent single-pole single-throw (SPST) analog switches integrated into a single monolithic CMOS structure.
• Low on-resistance of 35 Ohms with minimal variation over the analog signal range for accurate signal transmission.
• Fast switching action with reduced charge injection, simplifying sample-and-hold circuit designs.
• TTL and CMOS compatible digital inputs allowing direct interfacing with standard logic families.

Analog Switches, Multiplexers, Demultiplexers Applications

• Sample-and-hold circuits requiring low charge injection and fast settling times.
• Data acquisition systems utilizing high-speed analog signal routing.
• Industrial process control applications involving signal multiplexing.
• Instrumentation equipment requiring precise analog signal switching.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DYZ' corresponds to the SOIC-Narrow-16 package and Reel/Cut Tape carrier type as listed in distributor specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements prior to PCB assembly planning. Ensure the ordering quantity matches the available factory packaging options such as reels or cut tape formats provided by authorized suppliers.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG412DYZ when a quad SPST configuration with positive logic control is required. Compare the 35 Ohm on-resistance against higher resistance alternatives if lower insertion loss is critical. Consider the 44V maximum supply capability for applications handling larger signal swings compared to standard 5V-only switches. Verify that the 16-SOIC package dimensions fit the designated footprint on the target printed circuit board layout.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG412DYZ belongs to the DG412 series of monolithic CMOS analog switches from Renesas. It serves as a drop-in replacement for older DG212 series devices while offering improved performance metrics. The component is part of a broader family including DG411 and DG413 variants which differ primarily in logic polarity and channel configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411DYZ is functionally similar but utilizes negative logic for switch activation. The ADG412BRZ from Analog Devices offers comparable specifications in a 16-SOIC package. Verify pinout compatibility and logic polarity differences before substituting these parts in existing designs.
