Overview
The SN74LVC1G66DRLRG4 is a single-channel analog switch IC from Texas Instruments, belonging to the SN74LVC1G66 series. It features a SPST configuration housed in a SOT-5X3-5 package for surface mount installation. The device operates on a single supply voltage ranging from 1.65 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 10 Ohms, a maximum propagation delay (turn-on) of 4.2 ns, and a maximum turn-off time of 5 ns. It supports a switch DC current of 100 mA with a maximum power supply current of 100 nA. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides low on-resistance signal path control suitable for high-speed data switching applications.
- Operates across a wide single-supply voltage range compatible with various logic families.
- Features compact packaging designed for space-constrained surface-mount designs.
Applications
- Portable equipment requiring efficient power management and signal routing
- Cellular telephones for antenna switching and audio path selection
- Battery-powered systems utilizing low-voltage operation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure that the requested variant matches the required RoHS compliance status and moisture sensitivity level defined in the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a single SPST analog switch is required with low on-resistance and fast switching speeds. Consider the SOT-5X3-5 package constraints for PCB layout. Verify that the system voltage remains within the 1.65 V to 5.5 V range and that the thermal environment stays within the specified industrial temperature limits.
Part Context
This part belongs to the SN74LVC1G66 family of single analog switches. It shares functional similarities with other LVC series components but is distinct in its specific pinout and analog switching characteristics compared to digital logic gates or bus transceivers within the same product line.
Replacement Considerations
Consult the official datasheet for confirmed substitute part numbers. Cross-reference pinouts and electrical specifications carefully if considering alternatives from other manufacturers.
