Overview
The DG442DYZ-T is a monolithic CMOS analog switch integrated circuit manufactured by Renesas Electronics Corporation. It contains four independent single-pole single-throw (SPST) normally open switches within a 16-pin SOIC-N package. The device supports single supply voltages from 5V to 34V or dual supplies from ±5V to ±22V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum turn-on time of 250ns, and a maximum turn-off time of 210ns. It operates within a temperature range of -40°C to +85°C and features low charge injection of -1pC.
Feature Summary
- Integrates four independent SPST analog switches in a compact surface-mount package.
- Features TTL and CMOS compatible digital inputs for flexible logic interfacing.
- Utilizes high-voltage silicon-gate process technology with epitaxial layer to prevent latch-up.
Applications
- Data acquisition systems requiring signal routing.
- Sample and hold circuits benefiting from reduced charge injection.
- Industrial control systems operating in extended temperature environments.
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements against current datasheet revisions. Ensure the supplier provides valid traceability documentation for the Renesas Electronics Corporation origin.
Selection Notes
Select this component over similar series devices based on the specific requirement for 85 Ohm on-resistance and standard switching speeds. Compare against DG412 variants if lower on-resistance (35 Ohm) or faster switching times are required. Verify that the 16-SOIC package dimensions fit the target PCB footprint constraints.
Part Context
This part belongs to the DG44x series of monolithic CMOS analog switches. It serves as a functional equivalent to older discrete switch solutions but offers improved matching and lower power consumption. The DG442 specifically denotes the normally open configuration with four channels.
Replacement Considerations
DG442DYZ is the tube-packaged equivalent of this reel-part. DG412DYZ offers lower on-resistance (35 Ohm) and faster switching but differs in logic polarity characteristics relative to its counterpart DG411.
