Overview
The MC74VHC1GT66DF2G is a single-channel analog switch from onsemi's 74VHC series, housed in a SC-88A (SOT-353) surface-mount package. It operates on a single supply voltage ranging from 2 V to 5.5 V. The device features a maximum on-resistance of 40 Ohms and supports high-speed signal switching with propagation delays of 25 ns for both rise and fall times. It functions as an SPST normally-open switch with low off-state leakage current of 100 nA. The component is rated for an extended industrial temperature range from -55°C to +125°C.
Feature Summary
- High-speed signal routing capability within the 74VHC logic family
- Low power consumption with minimal quiescent current draw
- Wide operating voltage compatibility for diverse system interfaces
Applications
- Portable battery-powered equipment requiring low voltage operation
- Signal path switching in consumer electronics
- Communication systems utilizing high-speed data lines
Procurement Notes
Verify the specific suffix DF2G against official onsemi documentation to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration. Check for any product change notices regarding availability or manufacturing location updates before finalizing procurement plans.
Selection Notes
Select this component when a compact single-pole single-throw analog switch is required for signals up to 5.5 V. Ensure the application demands low on-resistance and fast switching speeds compatible with the 74VHC technology. Verify that the SC-88A package dimensions fit the available PCB real estate constraints.
Part Context
This part belongs to the MC74VHC1Gxx series of single-function CMOS analog switches. It shares the same core electrical characteristics as other variants in the series but differs in packaging or tape-and-reel specifications defined by the suffix. The device utilizes advanced silicon gate technology for high density and low power.
Replacement Considerations
Direct replacements include MC74VHC1G66DFT2G or MC74VHC1G66DTT1G. Cross-brand equivalents such as Nexperia 74VHC1G66 may be considered if pin-compatible and electrically equivalent.
