Overview
The NLAST4051QSR is an analog multiplexer/demultiplexer fabricated in sub-micron Silicon Gate CMOS technology. It features a single-pole, eight-position configuration plus a common off state. The device supports single supply operation from 3.0 V to 5.5 V or dual supply operation up to ±3 V. Key electrical parameters include a maximum on-resistance of 86 Ω at 3.0 V and 26 Ω at 4.5 V. The transition time ranges from 23 ns to 40 ns depending on voltage. Operating temperature spans -55°C to +125°C.
Feature Summary
- Pin-for-pin replacement for industry standard MAX4051 devices
- Address and inhibit logic are over-voltage tolerant up to 6 V
- Improved linearity and lower on-resistance compared to HC4051
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching
- Process control system I/O modules
Procurement Notes
Verify the QSOP-16 package suffix matches the specific design requirements. Confirm that the ordering code includes the QSR designation for tape and reel packaging. Ensure compatibility with existing PCB footprints before finalizing procurement orders.
Selection Notes
Select this component when low on-resistance and high bandwidth are required for analog signal paths. The TTL-compatible address inputs simplify interface logic. Verify power supply constraints align with the specified 3.0 V to 5.5 V operating range.
Part Context
This part belongs to the NLAS4051 series of analog switches. It serves as an improved version of the MC14051 and MC74HC4051. The series offers enhanced performance metrics while maintaining standard pin configurations for easy integration into legacy designs.
Replacement Considerations
Direct replacements include the MAX4051 and MAX4051A. Other compatible parts within the family are the NLAS4051 and MC74HC4051. Verify package dimensions and thermal characteristics when substituting.
