Overview
The MM74HC4066MX is a quad analog switch utilizing advanced silicon-gate CMOS technology. It features low on-resistance and low off-leakage currents, with bidirectional signal paths allowing any input to function as an output. The device includes linearization circuitry to reduce on-resistance variation and improve linearity. It supports analog signals up to 12V peak controlled by digital signals of the same range. Each switch has an independent control input that disables the channel when low. Inputs and outputs are protected against electrostatic discharge via diodes to VCC and ground.
Feature Summary
- Bidirectional switching capability for flexible signal routing
- Integrated linearization circuitry for improved signal fidelity
- Independent control inputs for individual channel management
Applications
- Signal routing in data acquisition systems
- Audio signal path switching
- Multiplexing sensor inputs
Procurement Notes
Verify the manufacturer designation, as Fairchild Semiconductor operations were acquired by ON Semiconductor. Confirm the specific ordering suffix matches the required package type and tape-and-reel specifications. Ensure the component meets current RoHS compliance standards required for the target assembly process.
Selection Notes
Select this component for applications requiring low distortion analog switching within a 0V to 12V range. Compare the typical 30 ohm on-resistance against load requirements. Verify that the 80 microampere maximum quiescent current aligns with power budget constraints. Ensure the SOIC-14 package fits the available PCB footprint.
Part Context
This part belongs to the 74HC logic family, offering compatibility with standard high-speed CMOS devices. It serves as a functional equivalent to other quad bilateral switches like the 74HC4066. The MX suffix typically indicates a tape and reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
SN74HC4066NSR from Texas Instruments offers pin-compatible functionality. MM74HC4066MTC provides alternative packaging options within the same series.
