Overview
The SN74AHC4066NG4 is a quad bilateral analog switch manufactured by Texas Instruments, belonging to the AHC logic family. It features four independent SPST switches in a 14-pin PDIP package. The device operates with a supply voltage range of 2 V to 5.5 V and supports CMOS/TTL input levels. Key electrical parameters include an on-resistance of typically 15 ohms at 5 V, low off-state leakage current, and propagation delays of approximately 12 ns. It functions as a bidirectional switch for analog signal routing within industrial and consumer applications.
Feature Summary
- Quad bilateral analog switching configuration
- Compatible with CMOS and TTL logic families
- Low on-resistance for efficient signal transmission
- Bidirectional data flow capability
Applications
- Analog signal multiplexing and demultiplexing
- Audio and video signal routing
- Data acquisition systems
- Battery management systems
Procurement Notes
Verify the specific ordering suffix 'G4' against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead-free status. Ensure the PDIP-14 package matches the target PCB footprint requirements. Cross-reference the part number with official Texas Instruments documentation to validate availability and any potential lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when a quad SPST analog switch is required with AHC speed and low power consumption. Compare on-resistance values and leakage currents against alternative logic families like HC or LV if specific impedance matching or ultra-low power is critical. Confirm that the 14-pin DIP package fits the assembly constraints compared to surface-mount alternatives.
Part Context
This part belongs to the SN74AHC4066 series of analog switches. The 'G4' suffix typically indicates environmental compliance, specifically RoHS and lead-free manufacturing standards. It serves as a general-purpose solution for switching analog signals in digital circuits, bridging the gap between pure digital logic and analog signal paths.
Replacement Considerations
The SN74AHC4066N is a direct functional equivalent without the environmental suffix. Other compatible parts include the SN74LV4066 for lower voltage operation and the CD74HC4066 for HC family compatibility. Verify pinout and electrical characteristics before substituting.
