Overview
The DG442DYZ is a monolithic quad single-pole single-throw (SPST) normally open CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent switches in a 16-pin SOIC-Narrow package. The device supports single supply voltages from 5 V to 34 V or dual supplies from ±5 V to ±22 V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum operating speed of 250 ns for turn-on and 210 ns for turn-off, and a maximum power supply current of 100 uA. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches with normally open configuration
- Supports both single-ended and split power supply operation
- Features low power consumption suitable for battery-powered applications
- Compatible with standard TTL and CMOS logic levels
Applications
- Data acquisition systems requiring signal routing
- Industrial process control signal switching
- Audio and video signal path selection
- Communication equipment interface switching
Procurement Notes
Verify the specific suffix DYZ corresponds to the 16-SOIC narrow package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Ensure the ordering information matches the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical characteristics.
Selection Notes
Select this component when four independent signal paths are required in a compact surface-mount footprint. Compare on-resistance specifications against other series members if lower resistance is critical for signal integrity. Verify that the 85 Ohm maximum on-resistance meets the voltage drop requirements of the target application circuit under expected load conditions.
Part Context
This part belongs to the DG44x series of high-performance CMOS analog switches. It shares functional similarities with the DG441 and DG444 but differs in internal logic polarity and switching speeds. The DG442 specifically utilizes negative logic for all four channels, distinguishing it from mixed-logic variants within the broader family.
Replacement Considerations
The DG442DVZ serves as a pin-compatible alternative utilizing a TSSOP-16 package instead of the SOIC-Narrow form factor. Other series members like the DG441 or DG444 may require logic inversion or offer different switching speeds. Verify package dimensions and thermal characteristics when substituting.
