Overview
The DG442DVZ is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It operates within a single supply voltage range of 5 V to 34 V or dual supplies of ±5 V to ±22 V. The device features a maximum on-resistance of 85 Ohms and supports a DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 250 ns and a maximum turn-off time of 210 ns. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a 16-TSSOP surface-mount package.
Feature Summary
- Integrates four independent SPST switches for signal routing
- Supports both single and dual power supply configurations
- Provides low charge injection characteristics
- Offers high off-isolation performance
Applications
- Data acquisition systems
- Process control modules
- Audio and video signal switching
Procurement Notes
Verify the specific suffix 'DVZ' corresponds to the 16-TSSOP package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the ordering part number matches the exact manufacturer designation to avoid package mismatches during procurement.
Selection Notes
Select this component when a quad SPST configuration is required with moderate on-resistance. Compare against the DG442DYZ if a SOIC package is preferred instead of TSSOP. Evaluate the DG441 series if normally closed contacts are needed rather than normally open. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the application circuit.
Part Context
This part belongs to the DG442 family of analog switches, which includes variants like the DG442DYZ in SOIC packaging. The DG442 series is designed for general-purpose analog signal switching applications requiring low power consumption and fast switching speeds. It serves as a key interface component in mixed-signal systems.
Replacement Considerations
The DG442DYZ is a direct pin-compatible alternative offering identical electrical specifications but packaged in 16-SOIC instead of TSSOP. Other similar quad SPST switches may require schematic review due to potential differences in pinout or package dimensions.
