Overview
The NLAST4052QSR is a TTL-compatible, double-pole, 4-position analog multiplexer/demultiplexer fabricated in sub-micron Silicon Gate CMOS technology. It features improved RDS(on) resistance and linearity compared to standard HC4052 devices. The device supports single supply operation from 3.0 V to 5.5 V or dual supply operation up to ±3 V, enabling the passage of 6 Vpp signals without coupling capacitors. Address and Inhibit pins are over-voltage tolerant, allowing them to be driven up to +6 V regardless of VCC.
Feature Summary
- Pin-for-pin replacement for industry standard MAX4052 and MAX4052A versions
- Address and Inhibit pins feature standard TTL compatibility with improved noise margins
- Digital inputs are over-voltage tolerant, supporting logic levels up to +6 V independent of VCC
- Capable of interfacing with 1.8 V logic when operating at VCC voltages between 3.0 V and 3.3 V
Applications
- Signal routing in systems requiring direct interface with 1.8 V logic families
- Replacing legacy MAX4052 components in existing designs without layout changes
- Dual-supply applications requiring transmission of large signal swings without external coupling capacitors
Procurement Notes
Verify that the ordering suffix QSR corresponds to the QSOP-16 package type as specified in the official datasheet. Confirm that the component meets the required RoHS compliance standards before integration into the final assembly. Ensure proper handling procedures are followed during storage and installation to maintain device reliability.
Selection Notes
Select this component when an exact pin-compatible substitute for the MAX4052 is required. It is suitable for designs needing improved on-resistance characteristics and enhanced linearity over standard HC4052 alternatives. Consider its specific voltage tolerance capabilities if the system involves mixed-voltage digital control interfaces.
Part Context
This part belongs to the NLAST series of analog switches manufactured by onsemi. It serves as an advanced iteration of the classic MC14052 architecture, utilizing modern sub-micron CMOS processes to achieve lower power consumption and faster switching speeds while maintaining backward compatibility with established industry footprints.
Replacement Considerations
Direct pin-for-pin replacements include the MAX4052 and MAX4052A. Designers should verify that the electrical parameters of the substitute meet the specific requirements of the application circuit.
