Overview
The SN74AHC4066DR is a quad bilateral switch manufactured by Texas Instruments, belonging to the AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and features four independent switches in a 14-pin SOIC package. Each switch provides low on-resistance and supports bidirectional signal flow controlled by separate enable inputs. The device ensures low leakage current when disabled and maintains compatibility with standard CMOS logic levels across the specified temperature range of -40°C to +85°C.
Feature Summary
- Quad configuration providing four independent bilateral switches for flexible signal routing
- Bidirectional data transfer capability allowing signals to pass in either direction between pins
- Low on-resistance characteristic ensuring minimal signal attenuation during conduction
- High input impedance and low leakage current when switches are in the off state
Applications
- Analog signal switching in multiplexer circuits
- Data bus isolation and protection interfaces
- Audio and video signal path selection systems
- Programmable gain amplifier input routing
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with official Texas Instruments documentation to validate authenticity and avoid counterfeit risks during sourcing.
Selection Notes
Select this component when designing circuits requiring multiple analog switches controlled by digital logic signals. The AHC series offers faster switching speeds compared to legacy HC devices while maintaining 5V tolerance. Consider the SOIC-14 package dimensions for PCB layout constraints and verify that the operating voltage aligns with the system power supply rails.
Part Context
This part belongs to the SN74AHC4066 family of quad bilateral switches. It serves as a digital-controlled analog switch solution, distinct from logic gates or memory elements. The DR suffix indicates a specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.
