Overview
The SN74LVC1G66DBVRE4 is a single bilateral analog switch from Texas Instruments, designed for operation within a 1.65 V to 5.5 V supply voltage range. It supports bidirectional signal transmission with amplitudes up to 5.5 V (peak), handling both analog and digital signals. The device features a maximum on-resistance of 10 Ohms, ensuring low signal attenuation. Key timing parameters include a maximum turn-on time of 4.2 ns and a maximum turn-off time of 5 ns. It operates reliably across an extended temperature range from -40 °C to +85 °C and is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- Supports bidirectional transmission of analog and digital signals up to 5.5 V peak amplitude
- Low on-resistance of 10 Ohms maximizes signal integrity
- Operates on a single supply voltage ranging from 1.65 V to 5.5 V
- High-speed switching with turn-on times as fast as 4.2 ns
Applications
- Wireless devices
- Audio and video signal routing
- Portable computing equipment
- Wearable devices
- Signal gating, chopping, modulation, or demodulation
Procurement Notes
Verify the E4 suffix indicates lead-free compliance and specific manufacturing lot codes per Texas Instruments documentation. Confirm the active status and availability through authorized distributors. Ensure the SOT-23-5 footprint matches the PCB design requirements. Check for RoHS compliance certificates if required by regional regulations. Validate that the operating temperature range meets the environmental constraints of the final assembly.
Selection Notes
Select this component when a single-channel bilateral switch is required for low-voltage applications. The 1.65 V minimum supply makes it suitable for battery-powered systems. Compare the 10 Ohm on-resistance against system loss budgets. Consider the 4.2 ns switching speed for high-frequency signal routing needs. Ensure the SOT-23-5 package size fits the spatial constraints of the design.
Part Context
This part belongs to the SN74LVC1G66 family of single analog switches. The DBVR suffix denotes the SOT-23-5 tape and reel packaging format. The E4 suffix typically signifies lead-free material composition and specific manufacturing origin details defined by Texas Instruments. It is a general-purpose CMOS analog switch designed for portable and consumer electronics.
Replacement Considerations
Direct pin-compatible replacements within the same LVC family should be verified against the datasheet for identical electrical characteristics. Cross-reference the on-resistance and leakage current specifications to ensure functional equivalence. Confirm that any substitute maintains the same 1.65 V to 5.5 V operating voltage range and SOT-23-5 package dimensions.
