Overview
The DG381ACWE is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a maximum on-resistance of 50 Ohms and supports dual supply voltages ranging from ±5V to ±18V, or a single supply from 10V to 30V. The device features a maximum turn-on time of 300 ns and a turn-off time of 250 ns. It is housed in a 16-SOIC package and functions within an operating temperature range of 0°C to +70°C. The component draws a maximum supply current of 500 uA and handles a DC switch current of 30 mA.
Feature Summary
- Dual SPST configuration for independent signal routing
- CMOS technology ensuring low power consumption
- TTL/CMOS logic compatibility for control interfaces
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal switching
- Instrumentation input selection
Procurement Notes
Verify the obsolete status of this component before design finalization. Confirm RoHS compliance requirements against specific project standards, as legacy versions may differ. Ensure the 16-SOIC package dimensions match the target PCB footprint. Validate that the 0°C to +70°C industrial temperature range meets environmental specifications.
Selection Notes
Select this part when dual isolated channels are required with moderate speed and low on-resistance. Compare charge injection and leakage current specifications against alternative switches if precision is critical. Ensure the voltage supply rails align with the ±5V to ±18V operational limits defined in the datasheet.
Part Context
This component belongs to the DG381A series of analog switches. It shares functional similarities with other devices in the Maxim Integrated portfolio designed for general-purpose signal switching applications. The wide SOIC package facilitates surface-mount assembly in compact electronic designs.
Replacement Considerations
Direct substitutes include the DG381ACWE+ variant which adheres to updated environmental standards. Other compatible options within the same family should be evaluated based on pinout compatibility and electrical parameter equivalence.
