Overview
The MM74HC4052SJX is a dual 4-channel analog multiplexer/demultiplexer implemented in advanced silicon-gate CMOS technology. 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 (E). The device operates within a supply voltage range of 2.0 V to 10.0 V. When enabled, the selected channel exhibits low on-resistance, while disabled channels enter a high-impedance state. The component supports bidirectional signal flow and includes built-in clamp diodes for ESD protection.
Feature Summary
- Dual 4-channel analog switching architecture
- Bidirectional data transmission capability
- Low on-resistance for minimal signal attenuation
- High noise immunity due to CMOS construction
Applications
- Data acquisition systems requiring channel selection
- Audio signal routing and switching
- Programmable gain amplifier configurations
- Instrumentation front-end multiplexing
Procurement Notes
Verify the specific suffix SJX against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the ordering information matches the exact part number variant required for your design, as suffixes may indicate differences in packaging or temperature ratings without altering the core electrical function.
Selection Notes
Select this component when a dual 4:1 analog switch is needed with standard HC logic compatibility. Verify that the supply voltage range of 2V to 10V aligns with the system power rails. Consider the on-resistance and leakage current specifications relative to the signal integrity requirements of the application.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with other manufacturers' 74HC4052 variants, such as those from NXP or Texas Instruments, provided pinouts and electrical characteristics are verified. The SJX suffix typically denotes a specific surface-mount package configuration offered by Fairchild Semiconductor.
Replacement Considerations
Direct replacements include the SN74HC4052 from Texas Instruments or the MC74HC4052 from onsemi. Verify pinout compatibility and ensure that the replacement part meets the same voltage and current specifications before substitution.
