Overview
The NLAS3257AMU3TCG is a dual SPDT analog switch and multiplexer/demultiplexer manufactured by onsemi. It operates within a voltage range of 1.6 V to 5.5 V, ensuring compatibility with various logic families. The device features low on-resistance (RON) of 9.3 Ω and high-speed performance with a propagation delay (tPD) of 0.25 ns at VCC = 4.5 V. Packaged in a compact 6-UDFN (1x1 mm) footprint, it supports bidirectional signal switching. Key electrical parameters include RON: 9.3 Ω, tPD: 0.25 ns, and operating voltage: 1.6 V to 5.5 V.
Feature Summary
- Dual SPDT configuration for efficient signal routing
- High-speed operation with minimal propagation delay
- Low on-resistance for reduced signal loss
- Compact UDFN package design
Applications
- Signal path switching in portable electronics
- Multiplexing/demultiplexing in data acquisition systems
- Audio/video signal routing
- Battery-powered devices requiring low power consumption
Procurement Notes
Verify the exact ordering suffix matches the required package and tape/reel specifications. Confirm RoHS compliance status and lead-free requirements align with project standards. Cross-reference the manufacturer datasheet for any recent updates to electrical characteristics or recommended operating conditions before finalizing procurement orders.
Selection Notes
Select this component when dual independent SPDT switching is required in space-constrained designs. Consider the 9.3 Ω on-resistance for signal integrity needs and the 0.25 ns propagation delay for high-speed applications. Ensure the 1.6 V to 5.5 V supply range matches the system's available voltage rails and logic levels.
Part Context
This part belongs to onsemi’s NLAS3257 series of analog switches, designed for general-purpose signal routing. The series offers a balance of speed, low resistance, and small form factor. The MU3TCG suffix indicates specific packaging and handling configurations suitable for automated assembly processes in consumer and industrial electronics manufacturing.
Replacement Considerations
Check for direct pin-compatible alternatives from onsemi or other manufacturers offering similar RON and tPD specs. Verify that any substitute maintains the same 6-UDFN footprint and voltage range. Consult official cross-reference guides for confirmed compatible parts.
