Overview
The SN74LVC1G66DBVR is a single bilateral analog switch manufactured by Texas Instruments, designed for operation with a supply voltage range of 1.65 V to 5.5 V. 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 and offers low off-state channel capacitance of 6 pF. Switching performance includes a maximum turn-on time of 4.2 ns and a maximum turn-off time of 5 ns. It operates within a temperature range of -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 across the passband
- Minimal off-state leakage current of 100 nA ensures effective signal isolation when disabled
Applications
- Wireless devices requiring signal routing
- Audio and video signal routing systems
- Portable computing equipment
- Wearable devices
- Signal gating, chopping, modulation, or demodulation in modems
- Signal multiplexing in ADC and DAC systems
Procurement Notes
Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific ordering suffix matches project requirements, as variations may exist. Ensure compliance with RoHS directives and check for automotive AEC-Q100 certification if applicable to the target environment. Validate packaging details against official datasheets prior to procurement.
Selection Notes
Select this component for applications requiring a single SPST analog switch with low on-resistance and wide voltage compatibility. The SOT-23-5 package suits space-constrained designs. Consider the 10 Ohm on-resistance and 6 pF off-capacitance for high-frequency signal paths. Ensure the operating temperature range aligns with environmental conditions.
Part Context
This part belongs to the SN74LVC1G66 series of single bilateral analog switches from Texas Instruments. It is part of the broader LVC logic family, characterized by low voltage CMOS technology. The device serves as a fundamental building block for signal switching in mixed-signal circuits, offering a compact solution compared to discrete transistor switches.
Replacement Considerations
Direct replacements include other SN74LVC1G66 variants such as SN74LVC1G66DBVT. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with similar single-channel analog switches from other manufacturers only if parameters match exactly.
