Overview
The MC74VHC1G66DFT2G is a single-channel analog switch IC from onsemi's 74VHC series, housed in a SOT-353-5 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 both turn-on and turn-off times limited to 25 ns. It functions within an extended temperature range of -55°C to +125°C. Power dissipation is rated at 150 mW, with a maximum supply current of 100 nA.
Feature Summary
- Provides high-speed analog signal routing capabilities suitable for data acquisition systems.
- Operates efficiently with low power consumption due to minimal supply current requirements.
- Ensures reliable performance across wide industrial temperature extremes.
Applications
- Portable battery-powered equipment requiring efficient power management
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
Procurement Notes
Verify the complete part number suffix, as the provided input lacks the final 'G'. Manufacturer documentation indicates that ordering suffixes define specific packaging or tape-and-reel configurations. Confirm availability status directly with onsemi, as this component may be subject to end-of-life notices or restricted distribution channels depending on the specific manufacturing lot and region.
Selection Notes
Select this component when a single SPST analog switch is required for signals up to 5.5 V. Ensure the application demands low on-resistance and fast switching speeds under 25 ns. Verify that the system can accommodate the SOT-353-5 footprint and that the thermal dissipation limits are respected within the operating environment.
Part Context
This device belongs to the 74VHC logic family, characterized by high-speed CMOS technology. It is designed for applications requiring fast switching and low power consumption. The product line includes various logic functions, with this specific model dedicated to analog signal routing tasks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult onsemi technical support for direct replacements or verify compatibility with other single-channel analog switches from the same manufacturer if pin-out compatibility is required.
