Overview
The DG441DVZ is a monolithic quad single-pole single-throw (SPST) normally-closed analog switch manufactured by Renesas Electronics Corporation. It utilizes high-voltage silicon-gate CMOS technology to provide four independent bilateral switches in a 16-pin TSSOP 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 Ω, a maximum operating speed of 250 ns for turn-on and 120 ns for turn-off, and a maximum power supply current of 100 µA. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Monolithic CMOS construction with high-voltage silicon-gate process
- Normally-closed (NC) configuration for four independent SPST channels
- TTL and CMOS compatible digital input logic
- Epitaxial layer design prevents latch-up issues
Applications
- Sample and hold circuits
- Data acquisition systems
- Automatic test equipment
- Communication systems
Procurement Notes
Verify the specific suffix 'DVZ' corresponds to the TSSOP-16 tube packaging format when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the component matches the Renesas/Intersil origin to avoid counterfeit risks associated with legacy CMOS analog switches.
Selection Notes
Select this component when a normally-closed signal path is required, as opposed to the normally-open DG440 series. Compare the 85 Ω on-resistance against the lower resistance options available in the DG411 series if signal integrity at higher currents is critical. Verify that the 250 ns switching speed meets the system timing requirements for the intended application bandwidth.
Part Context
The DG441DVZ belongs to the DG441 family of monolithic CMOS analog switches. It serves as a functional counterpart to the DG440, differing primarily in the default state of the switches. This part is part of Renesas's broader portfolio of interface and switching ICs derived from Intersil technology.
Replacement Considerations
The DG411 series offers similar functionality but features lower on-resistance (35 Ω) and faster switching speeds. The DG440 series provides identical pinouts and specifications but uses normally-open switches instead of normally-closed.
