Overview
The Nexperia 74AHC1G66GW,165 is a single-pole, single-throw analog switch housed in a TSSOP5 (SOT353-1) package. It operates on a supply voltage range of 2.0 V to 5.5 V with an overvoltage-tolerant enable input up to 5.5 V. The device features very low ON resistance, typically 26 Ω at 3.0 V and 14 Ω at 5.5 V. It supports bidirectional signal transmission between two independent terminals controlled by a digital logic level. Operating temperatures are specified from -40 °C to +125 °C.
Feature Summary
- Overvoltage tolerant control input for mixed voltage environments
- Bidirectional analog signal switching capability
- High noise immunity with CMOS low power dissipation
Applications
- Signal routing in mixed voltage systems
- Data acquisition signal path selection
- Audio and video signal switching
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration. Ensure that the component marking code matches the datasheet specifications for the 74AHC1G66GW variant before finalizing procurement orders.
Selection Notes
Select this component when a compact SPST analog switch is required for signals within the 2.0 V to 5.5 V range. The TSSOP5 package is suitable for space-constrained designs. Verify that the application does not require automotive qualification, as standard versions lack AEC-Q100 certification.
Part Context
This part belongs to the 74AHC1G66 family of single-pole, single-throw analog switches manufactured by Nexperia. The 'GW' designation specifically identifies the TSSOP5 plastic thin shrink small outline package variant. It serves as a fundamental building block for managing analog signal paths in portable and industrial electronics.
Replacement Considerations
The 74AHC1G66GV is a pin-compatible alternative available in the SC-74A (SOT753) package. Both variants share identical electrical characteristics and functionality, differing only in physical footprint dimensions.
