Overview
The NLAS4051QSR is a single-pole, eight-position analog multiplexer/demultiplexer fabricated in sub-micron Silicon Gate CMOS technology. It features improved on-resistance (RDS(on)) and linearity compared to standard HC4051 devices. The device supports single supply operation from 2.5 V to 5.5 V or dual supply operation up to ±3.0 V. Address and inhibit logic inputs are over-voltage tolerant, allowing drive voltages up to +6.0 V regardless of the supply voltage. It operates within a temperature range of -55°C to 125°C.
Feature Summary
- Sub-micron CMOS technology for low power consumption and high speed
- Over-voltage tolerant address and inhibit logic inputs
- Single or dual supply capability with wide operating voltage range
- Improved linearity and lower on-resistance than standard HC4051
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching
- Industrial process control instrumentation
- Communication equipment signal path selection
Procurement Notes
Verify the specific suffix 'QSR' corresponds to the QSOP-16 package and tape & reel shipping configuration as listed in the ordering information. Confirm that the component meets RoHS compliance requirements if necessary for your assembly process. Check for any automotive qualification markings if the application requires AEC-Q100 standards, although the datasheet primarily details general industrial specifications.
Selection Notes
Select this component when an 8-channel analog switch with TTL-compatible logic levels is required. Ensure the system voltage falls within the 2.5 V to 5.5 V single supply or ±3.0 V dual supply range. Consider the 26 Ω typical on-resistance at 5 V for signal integrity. Verify that the QSOP-16 package dimensions fit the PCB layout constraints.
Part Context
This part belongs to the NLAS4051 series of analog multiplexers. It serves as an improved version of the MC14051 and MC74HC4051, offering better performance metrics. The series includes variants in SOIC-16 and TSSOP-16 packages, providing flexibility for different board space and thermal requirements.
Replacement Considerations
The datasheet explicitly states pin-for-pin replacement for MAX4051 and MAX4051A. Designers should verify electrical parameters against these equivalents to ensure compatibility in existing designs.
