Overview
The MM74HC4066N is a quad bilateral analog switch manufactured by Fairchild Semiconductor, utilizing advanced silicon-gate CMOS technology. It features four independent single-pole single-throw (SPST) switches with individual control inputs. The device supports a wide analog input voltage range of 0V to 12V and operates on a supply voltage between 2V and 12V. Key electrical parameters include a typical ON resistance of 30Ω at 12V, maximum quiescent current of 80µA, and propagation delays ranging from 3ns to 25ns depending on voltage. It is housed in a 14-lead Plastic Dual-In-Line (PDIP) package.
Feature Summary
- Bidirectional signal transmission capability allowing any pin to function as input or output
- Integrated linearization circuitry for reduced ON resistance and improved linearity
- Individual control inputs for independent switching of each channel
- Built-in electrostatic discharge protection diodes connected to VCC and ground
Applications
- Signal routing in multiplexing and demultiplexing circuits
- Audio and video signal path switching
- Programmable gain amplifier configurations
- Sample-and-hold circuits
Procurement Notes
Verify the manufacturer origin, as Fairchild Semiconductor was acquired by onsemi. Confirm the specific package type matches the design requirements, as this component is available in multiple form factors including SOIC and TSSOP. Ensure the ordering code suffix aligns with the desired packaging format, such as tape and reel options if applicable.
Selection Notes
Select this component when a low ON resistance and high linearity are required for analog signal paths up to 12V. Consider the PDIP package for through-hole assembly needs. Evaluate the power dissipation limits and thermal derating characteristics if operating near the maximum temperature range of 85°C.
Part Context
This device belongs to the 74HC series of high-speed CMOS logic components. It is functionally compatible with other quad analog switches like the 74HC4066 but offers specific performance characteristics defined by Fairchild's manufacturing process. It serves as a standard solution for general-purpose analog switching applications requiring digital control.
Replacement Considerations
Direct pin-compatible substitutes include the 74HC4066 from various manufacturers. Verify that alternative sources meet the same ON resistance and leakage current specifications for critical analog applications.
