Overview
The NLAS4053QSR is a triple 2:1 analog switch-multiplexer fabricated in sub-micron Silicon Gate CMOS technology. It operates on single supplies of 3.0 to 5.5 V or dual supplies up to ±3.0 V, supporting 6 V peak-to-peak signals without coupling capacitors. The device features an improved RDS(on) of 86 Ω at 3.0 V and 37 Ω at 4.5 V (–55°C to 125°C). Address and inhibit pins are over-voltage tolerant up to +6 V regardless of VCC. Key AC characteristics include a maximum transition time of 45 ns at 2.5 V and off-channel isolation of –93 dB at 100 kHz.
Feature Summary
- Sub-micron CMOS process for low on-resistance and high linearity
- Dual supply operation capability with wide voltage tolerance
- Over-voltage tolerant address and control inputs
Applications
- Signal routing in audio and video equipment
- Data acquisition systems requiring multiplexing
- Programmable gain amplifiers and attenuators
Procurement Notes
Verify the specific suffix 'QS' corresponds to the QSOP-16 package configuration required for your PCB layout. Confirm that the component status aligns with long-term availability needs, as older logic families may face discontinuation risks. Ensure ESD handling protocols are followed during assembly due to the CMOS construction.
Selection Notes
Select this component when pin-for-pin compatibility with industry standard '4053' devices is required alongside improved electrical performance. It is suitable for designs needing lower on-resistance than standard HC4053 variants at 5.0 V. Consider the QSOP-16 package constraints if space-saving surface mount solutions are necessary for the application.
Part Context
This part belongs to the NLAS4053 family, which serves as an enhanced replacement for legacy MC14053 and MC74HC4053 devices. The series utilizes advanced silicon gate CMOS technology to achieve superior switching characteristics compared to previous generations, specifically targeting applications demanding better linearity and lower power consumption.
Replacement Considerations
Direct pin-for-pin replacements include the MAX4053 and MAX4053A. Standard equivalents such as the MC14053 and MC74HC4053 can be used, though they lack the improved on-resistance specifications of the NLAS4053 series.
