Overview
The SN74AHC4066N is a quadruple bilateral analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features four independent SPST channels. The device utilizes AHC logic series technology, providing low on-resistance and high switching speed. It is housed in a 14-pin PDIP package designed for through-hole mounting. The component supports an operating temperature range from -40°C to +85°C and delivers a maximum switch DC current capability.
Feature Summary
- Provides four independent single-pole single-throw (SPST) analog signal paths
- Supports bidirectional signal flow for flexible circuit routing
- Operates across a wide 2 V to 5.5 V power supply range
Applications
- Signal multiplexing and demultiplexing circuits
- Audio and video signal path switching
- Data acquisition systems requiring analog isolation
Procurement Notes
Verify the specific suffix 'N' confirms the PDIP-14 through-hole package variant. Confirm RoHS compliance status via official documentation. Ensure the ordering part number matches the exact manufacturer designation to avoid package or electrical specification mismatches during procurement.
Selection Notes
Select this component when through-hole mounting is required for quad analog switching. Compare on-resistance and leakage current specifications against PCB-mounted alternatives if space constraints allow. Verify that the 2 V to 5.5 V supply range aligns with the target system voltage requirements.
Part Context
This part belongs to the SN74AHC4066 family of quadruple bilateral switches. It shares functional similarities with other AHC series logic devices but is distinctively configured for analog signal routing rather than digital logic processing. The PDIP package distinguishes it from surface-mount variants like the DGGR or RGYR.
Replacement Considerations
SN74AHC4066DGGR: Surface-mount SOIC-14 equivalent. SN74AHC4066RGYR: Surface-mount VQFN-14 equivalent. SN74AC4066N: AC series through-hole alternative with different drive strength.
