Overview
The DG9454EEN-T1-GE4 is a triple SPDT analog switch manufactured by Vishay Siliconix. It operates from a V+ supply of 3 V to 16 V and a logic supply (VL) of 2.5 V to 5.5 V, ensuring 1.8 V logic compatibility. The device features low power consumption with I+ and IL less than 1 μA. Key electrical parameters include an on-resistance (RON) maximum of 103 Ω at room temperature for V+=12V, and a bandwidth of 356 MHz. Parasitic capacitance values are CD(ON): 8.8 pF, CD(OFF): 4 pF, and CS(OFF): 3.1 pF. It functions within a temperature range of -40 °C to +125 °C.

Procurement Notes
Verify the specific ordering suffix against current Vishay documentation to confirm package type and lead-free status. Confirm that the miniQFN-16 footprint matches the design requirements. Ensure the operating voltage ranges align with the system's power supply specifications before finalizing procurement.
Selection Notes
Select this component when a compact triple SPDT switch with low leakage and high bandwidth is required. The 1.8 V logic interface allows direct connection to low-voltage microcontrollers. Consider the thermal resistance and power dissipation limits if operating near the upper temperature extremes or maximum voltage ratings.
Part Context
This part belongs to the DG9454 series of low capacitance analog switches. It is designed for portable consumer applications and instrumentation where size and power efficiency are critical constraints. The device utilizes advanced CMOS technology to achieve its performance characteristics in a lead-free nickel-palladium-gold termination.
Replacement Considerations
Check for availability of DG9454EEN-T1-E4 as a potential alternative. Verify pinout compatibility and electrical parameter overlaps with other Vishay DG series devices before substitution.
