Overview
The NLAST4051DT is an analog multiplexer/demultiplexer manufactured by onsemi, utilizing advanced AST (Advanced Silicon Gate Technology) CMOS. It functions as a single 8-channel switch with three digital select inputs and one enable input. The device supports bidirectional signal flow between common and selected channels. It operates within a supply voltage range of 2.0V to 3.6V, ensuring compatibility with low-voltage logic systems. The component is housed in a compact surface-mount package suitable for space-constrained designs.
Feature Summary
- Utilizes AST CMOS technology for high-speed operation and low power consumption
- Supports bidirectional data transmission across eight independent channels
- Features low ON resistance to minimize signal attenuation
- Includes active clamp diodes on all inputs to handle fast-rising signals
Applications
- Portable battery-powered equipment requiring low voltage operation
- Signal routing in communication systems
- Data acquisition systems for channel selection
- Audio switching applications
Procurement Notes
Verify the specific ordering suffix to confirm packaging type, such as tape-and-reel or tube configuration. Ensure compliance with RoHS directives and check for lead-free status if required by assembly standards. Confirm the operating temperature range matches the environmental conditions of the target application before finalizing procurement.
Selection Notes
Select this component when a low-voltage, high-performance analog switch is required for 8-channel multiplexing. Compare ON resistance and leakage current specifications against system requirements. Consider the package size relative to available PCB real estate. Verify that the supply voltage range aligns with the system's power rails.
Part Context
This part belongs to the 4051 series of analog multiplexers from onsemi. It shares functional similarities with other industry-standard 8-channel switches but offers optimized performance through AST CMOS technology. The device is designed to replace older generation parts while providing improved speed and lower power dissipation in modern electronic circuits.
Replacement Considerations
Check pinout compatibility with existing designs. Verify electrical parameters such as ON resistance and bandwidth against alternative suppliers. Ensure the replacement part supports the same supply voltage range and package dimensions to maintain mechanical fit.
