Overview
The SN74AHC4066PWR is a high-speed CMOS quad 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 single-pole single-throw (SPST) switches in a TSSOP-14 package. Key electrical parameters include a maximum on-resistance of 75 Ohms, a maximum propagation delay of 12 ns, and a maximum power supply current of 20 uA. The device supports a maximum switching DC current of 50 mA and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides four independent bilateral analog switches for signal routing applications
- Operates with low power consumption suitable for battery-powered systems
- Features high-speed switching capabilities with minimal propagation delay
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Programmable gain amplifier input selection
Procurement Notes
Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest environmental files before procurement. Cross-reference the component marking code with the datasheet to authenticate the source and prevent counterfeit components during sourcing.
Selection Notes
Select this component when a quad SPST analog switch is required with a wide supply voltage range extending down to 2 V. Ensure the application demands a maximum on-resistance no higher than 75 Ohms and can accommodate the specified 50 mA switching current limit. Verify that the TSSOP-14 package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the SN74AHC4066 family of high-speed CMOS logic devices. It serves as the AHC variant of the legacy CD74HC4066, offering improved speed and lower power consumption while maintaining pin compatibility. The PWR suffix indicates surface-mount packaging in a TSSOP-14 form factor designed for automated assembly processes.
