DG381ACWE+T

Overview

The DG381ACWE+T is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of ±5V to ±18V for dual supplies or 10V to 30V for single supplies. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. Electrical performance includes a maximum turn-on time of 300 ns and a maximum turn-off time of 250 ns. Power consumption is limited to a maximum supply current of 500 uA. The component is housed in a 16-SOIC surface-mount package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual SPST configuration providing independent signal path control
• CMOS technology enabling low power consumption and TTL/CMOS logic compatibility
• Normally open state ensuring defined default signal isolation

Applications

• Signal routing in data acquisition systems
• Audio and video signal switching applications
• Process control instrumentation signal conditioning

Procurement Notes

Verify the specific suffix designation, as the base model DG381ACWE+ typically denotes tube packaging while the +T suffix indicates tape and reel configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notifications or product change notices that may affect long-term availability and manufacturing continuity.

Selection Notes

Select this component when dual isolated channels are required with moderate speed requirements. Ensure the application voltage does not exceed the 30V single-supply or ±18V dual-supply limits. Verify that the 50 Ohm on-resistance meets the signal integrity requirements for the specific load. Consider thermal dissipation capabilities if operating near the upper temperature limit.

Part Context

This part belongs to the DG381A series of general-purpose analog switches. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The wide SOIC package facilitates surface-mount assembly in compact circuit designs requiring multiple independent switching paths.

Replacement Considerations

Direct substitutes include the DG381ACWE+ variant which offers identical electrical specifications but utilizes tube packaging instead of tape and reel. Other members of the DG381 family may serve as functional replacements if pinout and electrical parameters align with the design requirements.
