DG445DYZ

Overview

The DG445DYZ is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) switches within a 16-pin SOIC-Narrow package. The device supports single or dual power supplies, operating from 5V to 34V for single supply and ±5V to ±20V for dual supply configurations. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum turn-on time of 250 ns, and a maximum turn-off time of 210 ns. The component functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

Features low charge injection characteristics that simplify sample-and-hold circuit applications.
Provides TTL and CMOS compatible digital inputs for flexible logic interfacing.
Utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latch-up.

Applications

Sample and hold circuits
Data acquisition systems
Automatic test equipment

Procurement Notes

Verify the specific suffix DYZ corresponds to the SOIC-Narrow-16 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet to maintain component reliability during assembly.

Selection Notes

Select this component for applications requiring drop-in replacement for older DG211/DG212 series devices. Consider the 85 Ohm on-resistance limit and 250 ns switching speed against system requirements. Verify that the ±20V dual supply capability aligns with the signal voltage ranges expected in the target design environment.

Part Context

This part belongs to the DG444/DG445 family of monolithic quad SPST CMOS analog switches. The DG445 variant specifically utilizes selection logic polarity distinct from the DG444 series, while sharing identical internal switch architecture and performance metrics.
