Overview
The DG445DVZ-T is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 5 V to 34 V for single supplies or ±5 V to ±22 V for dual supplies. The device features a maximum on-resistance of 85 Ohms and supports a continuous 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-TSSOP surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST switches within a single integrated circuit
- Supports both single and dual power supply configurations for flexible system design
- Provides low charge injection characteristics suitable for precision signal routing
Applications
- Data acquisition systems requiring multi-channel signal switching
- Industrial process control instrumentation
- Medical equipment signal path management
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation, as environmental declarations may vary by production batch. Ensure the 16-TSSOP footprint matches the target PCB layout dimensions before finalizing procurement orders.
Selection Notes
Select this component when a compact quad SPST configuration is required with moderate on-resistance specifications. The wide supply voltage capability allows compatibility with various logic levels. Consider the thermal dissipation limits inherent to the TSSOP package if high current loads are anticipated in the application design.
Part Context
This part belongs to the DG445 series of analog switches, which are designed for general-purpose signal routing applications. The DVZ variant specifically denotes the 16-pin Thin Shrink Small Outline Package (TSSOP). This series offers a balance between speed, power consumption, and channel density for embedded systems.
Replacement Considerations
The DG445DY-T1-E3 serves as a functional equivalent from Vishay/Siliconix. Verify pinout compatibility and package dimensions before substitution, as physical mounting requirements may differ between manufacturers despite identical electrical specifications.
