Overview
The MM74HC4052SJ is a dual 4-channel analog multiplexer/demultiplexer manufactured by Fairchild Semiconductor. It features two independent multiplexers, each with four inputs and one common output, controlled by shared digital select lines (S0, S1) and an active-low enable input. The device operates on a single supply voltage ranging from 2.0 V to 6.0 V or a dual supply configuration. It utilizes advanced CMOS technology to provide low ON resistance and high OFF isolation. The component is housed in a 16-lead Small Outline Package (SOIC), suitable for surface-mount applications.
Feature Summary
- Dual independent 4-to-1 analog switching capability
- Shared digital control logic for simplified interface
- Low ON resistance for efficient signal transmission
- High OFF isolation to minimize crosstalk
Applications
- Data acquisition systems requiring channel selection
- Audio signal routing and switching
- Programmable gain amplifier circuits
- Instrumentation front-end multiplexing
Procurement Notes
Verify the specific suffix SJ against the manufacturer's current product status, as legacy Fairchild parts may have transitioned to onsemi. Confirm RoHS compliance and lead-free specifications directly with the supplier. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when dual 4-channel analog switching is required within a standard 74HC logic family voltage range. Compare ON resistance and leakage current specifications against alternative manufacturers if strict signal integrity limits are imposed. Verify that the operating temperature range meets the environmental conditions of the intended application.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with other 74HC4052 variants from different manufacturers, such as NXP or Texas Instruments, provided pinouts and electrical characteristics align. The SJ suffix typically denotes a specific tape-and-reel packaging format for surface-mount assembly.
Replacement Considerations
Direct substitutes include the SN74HC4052 from Texas Instruments and the MC74HC4052 from onsemi. Verify pin compatibility and electrical parameter equivalence before substitution.
