DG441DYZ

Overview

The DG441DYZ is a monolithic quad SPST normally-closed analog switch manufactured by Renesas Electronics Corporation. It features four independent switches in a 16-lead SOIC-Narrow package. The device supports single supplies from 5V to 34V or dual supplies of ±5V to ±22V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum turn-on time of 250ns, and a maximum turn-off time of 120ns. It operates within a temperature range of -40°C to +85°C with a maximum supply current of 100uA.

Feature Summary

Four independent single-pole single-throw (SPST) channels configured as normally-closed switches
Compatible with TTL and CMOS digital logic inputs for control
High voltage silicon-gate process technology prevents latch-up

Applications

Sample and hold circuits
Data acquisition systems
Process control loops

Procurement Notes

Verify the suffix 'DYZ' corresponds to the specific 16-SOIC narrow package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly line. Ensure the normally-closed configuration matches the circuit design intent, as it differs from the DG442 series.

Selection Notes

Select this component when a normally-closed analog switching function is required. Compare against the DG442DYZ if a normally-open configuration is needed instead. Consider the DG411 series if lower on-resistance (35 Ohms) and faster switching speeds are necessary for the application.

Part Context

This part belongs to the DG44x family of high-voltage CMOS analog switches. It serves as a drop-in replacement for older DG211/DG212 series devices but offers improved performance characteristics such as reduced charge injection and lower power consumption due to advanced manufacturing processes.

Replacement Considerations

FAQ

What is the difference between DG441DYZ and DG442DYZ?

The primary difference is the switch state: DG441DYZ contains normally-closed (NC) switches, while DG442DYZ contains normally-open (NO) switches. All other electrical specifications and pinouts remain identical.
