Overview
The SN74AUC1G66YEAR is a single bilateral analog switch from the Texas Instruments 74AUC series, designed for signal gating and multiplexing. It operates within a supply voltage range of 0.8 V to 2.7 V, with specific optimization for 1.65-V to 1.95-V applications. The device handles both analog and digital signals between VCC and GND in either direction. Key electrical parameters include a typical on-state resistance of 9 Ω at 2.3 V and a maximum propagation delay of 0.2 ns at 1.8 V with a 15 pF load. It features low power consumption with a maximum supply current of 10 μA and high linearity.
Feature Summary
- Utilizes Texas Instruments NanoFree™ package technology, which integrates the die directly as the package to minimize size and enhance electrical performance.
- Provides sub-1-V operability and wide voltage support ranging from 0.8 V to 2.7 V, suitable for low-voltage portable systems.
- Offers robust protection against latch-up exceeding JESD 78 Class II standards and electrostatic discharge (ESD) protection exceeding JESD 22 requirements.
Applications
- Signal gating and chopping circuits
- Modulation and demodulation in modem applications
- Signal multiplexing for analog-to-digital and digital-to-analog conversion systems
Procurement Notes
Verify the exact suffix configuration when ordering, as the YEAR designation indicates a specific packaging or manufacturing variant within the SN74AUC1G66 family. Confirm that the selected package type matches the required footprint and thermal constraints for the target application design.
Selection Notes
Select this component for designs requiring minimal footprint and low on-state impedance in sub-2.7 V environments. Ensure control inputs are tied to valid logic levels to prevent floating states. Consider the specific package dimensions if board space is constrained by the NanoFree™ form factor.
Part Context
This part belongs to the SN74AUC1G66 product folder, representing a single-channel bilateral analog switch. It is distinct from buffer or driver variants within the broader 74AUC logic family, focusing specifically on analog signal routing rather than digital logic buffering.
Replacement Considerations
Direct functional equivalents within the same family include SN74AUC1G66DBVR, SN74AUC1G66DCKR, and SN74AUC1G66YZPR. Verify pinout compatibility and package dimensions before substituting, as physical footprints differ across SOT-23, SC-70, and DSBGA options.
