DG445CY+T

Overview

The DG445CY+T is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single supply voltage ranging from 10 V to 30 V or dual supplies from ±4.5 V to ±20 V. The device features a maximum on-resistance of 85 Ohms and supports a DC switch current of 30 mA. Electrical performance includes a maximum turn-on time of 250 ns and a maximum turn-off time of 120 ns. Power dissipation is rated at 696 mW, with a maximum supply current of 1 uA. It is housed in a 16-pin SOIC-Narrow package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates four independent SPST switches for signal routing applications
Supports both single and dual power supply configurations
Provides low quiescent current consumption

Applications

Signal multiplexing systems
Data acquisition circuits
Audio signal switching

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required thermal and electrical specifications for the target environment.

Selection Notes

Select this component for designs requiring multiple isolated analog paths. Verify that the load current does not exceed the 30 mA limit. Check that the system voltage remains within the specified 10 V to 30 V single supply range.

Part Context

This part belongs to the DG445 series of improved quad SPST analog switches. It shares functional similarities with other members of the family but differs in packaging and specific electrical tolerances. The CY+ designation identifies the commercial grade temperature range and lead-free construction.
