Overview
The MM74HC4066MTC is a quad bilateral analog switch manufactured by Fairchild Semiconductor, utilizing advanced silicon-gate CMOS technology. It features four independent SPST switches with individual control inputs. The device supports a wide analog input voltage range of 0V to 12V and operates on a single supply voltage typically between 2V and 6V. Key electrical parameters include a typical 'on' resistance of 30 ohms and a maximum quiescent current of 80 µA. The package is TSSOP-14, designed for surface mount applications.
Feature Summary
- Bidirectional signal path allowing any pin to function as input or output
- Integrated linearization circuitry to minimize on-resistance variation
- Individual digital control inputs for independent switch activation
- Electrostatic discharge protection diodes on all pins
Applications
- Signal routing in audio and video processing systems
- Data acquisition systems requiring analog multiplexing
- Programmable gain amplifier circuits
- Battery-powered portable equipment due to low power consumption
Procurement Notes
Verify the manufacturer origin carefully, as Fairchild Semiconductor's logic division was acquired by onsemi. Ensure the component matches the specific suffix requirements for your assembly process. Check RoHS compliance status against the latest datasheet revision. Confirm the package type is TSSOP-14 before ordering. Validate authenticity through authorized distribution channels.
Selection Notes
Select this component when a quad analog switch with low on-resistance is required. It is suitable for signals up to 12V peak. Compare with SN74HC4066 or CD74HC4066 for pin-compatible alternatives from other manufacturers. Consider the 80 µA quiescent current limit for battery life calculations. Ensure the operating temperature range meets system requirements.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with standard 74HC4066 specifications. The MM prefix indicates it is a commercial grade device from Fairchild. It serves as a direct replacement for older MC14066 or BU4066 designs in modern PCB layouts.
Replacement Considerations
SN74HC4066PWR (Texas Instruments) offers a similar quad analog switch in a TSSOP-14 package. CD74HC4066M (Texas Instruments) is another compatible alternative. Verify pinout compatibility and electrical parameter tolerances before substitution.
