DG444DYZ-T

Overview

The DG444DYZ-T is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation, housed in a 16-pin SOIC-N package. It integrates four independent single-pole single-throw (SPST) switches with TTL and CMOS compatible digital inputs. The device supports single supply voltages from 5V to 34V or dual supplies of ±5V to ±20V. Key electrical parameters include a maximum on-resistance of 85Ω, a maximum turn-on time of 250ns, and a maximum turn-off time of 140ns. It operates within a temperature range of -40°C to +85°C and features low power consumption of less than 35µW.

Feature Summary

Monolithic CMOS construction with four independent SPST channels
TTL and CMOS compatible digital input logic
Low charge injection for simplified sample and hold applications
Epitaxial layer design prevents latch-up associated with older CMOS technologies

Applications

Sample and hold circuits
Data acquisition systems
Automatic test equipment
Communication systems

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration distinct from tube variants. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the ordering part number matches the exact pinout and logic polarity requirements for the intended circuit design.

Selection Notes

Select this component when drop-in replacement for DG211/DG212 series is required with improved switching speed. Choose based on the 85Ω on-resistance limit and 140ns turn-off time specifications. Verify that the 34V maximum voltage rating aligns with the system's signal swing requirements.

Part Context

The DG444 series serves as an upgrade to the legacy DG211 and DG212 devices, offering lower on-resistance and faster switching times. It belongs to the broader family of monolithic quad SPST CMOS analog switches designed for high-voltage silicon-gate processes. The DG444 differs from the DG445 primarily in the polarity of its selection logic.
