Overview
The DG442DVZ-T is a monolithic quad single-pole single-throw (SPST) normally open CMOS analog switch manufactured by Renesas Electronics Corporation. It operates with a single supply voltage ranging from 5 V to 34 V or dual supplies from ±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 performance includes a maximum turn-on time of 250 ns and a maximum turn-off time of 210 ns. It is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Four independent SPST analog switches integrated into a single monolithic CMOS structure
- Compatible with TTL and CMOS digital logic inputs for flexible control interfacing
- Supports both single-ended and split power supply configurations for broad signal range coverage
Applications
- Data acquisition systems requiring signal routing
- Programmable gain amplifier circuits
- Sample and hold applications
Procurement Notes
Verify the suffix 'T' indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS3 compliance and moisture sensitivity level 3 requirements during storage and handling. Ensure the specific lot date code aligns with project timelines, as manufacturing lead times may vary based on production schedules.
Selection Notes
Select this component when four independent normally open channels are required in a surface-mount TSSOP-16 footprint. Compare against DG442DYZ if tube packaging is preferred. Verify that the 85 Ohm on-resistance meets circuit impedance requirements and that the 34 V single-supply limit accommodates the maximum signal swing.
Part Context
This part belongs to the DG442 series of monolithic quad SPST CMOS analog switches. It serves as a drop-in replacement for legacy devices like the DG212, offering improved switching speeds and lower charge injection. The series is designed for applications demanding low power consumption and high reliability in industrial and commercial environments.
Replacement Considerations
DG442DYZ offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel. DG442DVZ provides the same functionality in a standard TSSOP-16 package without the reel designation.
