Overview
The DG9454EN-T1-E4 is a multiplexer switch IC manufactured by Vishay Siliconix, housed in a QFN-16 package. It features two channels configured as three 2:1 multiplexers. The device operates on a single supply voltage ranging from 2.7 V to 12 V. Key electrical specifications include a maximum on-resistance of 137 Ohms, a maximum turn-on time of 250 ns, and a maximum turn-off time of 180 ns. It supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrates three independent 2:1 multiplexer paths within a dual-channel architecture for signal routing applications.
Applications
- Signal path selection in data acquisition systems
- Multiplexing sensor inputs in industrial control circuits
- Test and measurement equipment requiring analog signal switching
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure the specific suffix matches project requirements. Check current lifecycle status as availability may vary. Validate packaging details against procurement specifications before ordering.
Selection Notes
Select this component when a compact solution for multiple 2:1 signal paths is required within a 12 V single-supply environment. Consider the 137 Ohm on-resistance limit for signal integrity requirements. Evaluate the wide operating temperature range for harsh industrial conditions. Compare propagation delays against system timing constraints.
Part Context
This part belongs to the DG945x series of multiplexer switches from Vishay Siliconix. The series focuses on providing reliable analog signal routing in small form factors. The EN-T1-E4 designation indicates the specific pinout, tape-and-reel packaging, and environmental compliance variant within this product family.
Replacement Considerations
Publicly documented recommended alternatives include parts from the DG40 series. Verify pin compatibility and electrical parameter alignment before substitution. Consult official datasheets for functional equivalence confirmation.
