Overview
The SN74AUC1G66YZAR is a single bilateral analog switch manufactured by Texas Instruments, utilizing the NanoFree™ package technology. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.65 V to 1.95 V applications. The device handles both analog and digital signals with a maximum propagation delay of 0.2 ns at 1.8 V. Key electrical parameters include a typical on-state resistance of 9 Ω at 2.3 V, a maximum supply current of 10 μA, and an off-state leakage current of ±1 μA at 2.7 V. It features ESD protection exceeding JESD 22 standards and latch-up performance exceeding 100 mA per JESD 78 Class II.
Feature Summary
- Utilizes Texas Instruments NanoFree™ packaging technology, which integrates the die directly as the package to minimize footprint and enhance electrical performance.
- Provides high-speed signal switching with a maximum propagation delay of 0.2 ns under standard test conditions.
- Features low on-state impedance, typically 9 Ω, ensuring minimal signal attenuation during conduction.
- Supports sub-1-V operation and includes robust ESD protection exceeding human-body and charged-device model standards.
Applications
- Signal gating and chopping circuits
- Modulation and demodulation in modem systems
- Signal multiplexing for analog-to-digital conversion systems
- Signal multiplexing for digital-to-analog conversion systems
Procurement Notes
Verify the specific ordering suffix 'YZAR' against the latest TI Package Option Addendum to confirm availability status and reel specifications. Ensure the component matches the required DSBGA (YZP) package dimensions and pin configuration for PCB layout compatibility. Confirm RoHS compliance and moisture sensitivity level ratings prior to assembly planning.
Selection Notes
Select this component when a compact, low-voltage analog switch is required for high-speed signal routing. The NanoFree™ package is suitable for space-constrained designs. Ensure the operating voltage remains within the 0.8 V to 2.7 V range and that the load capacitance does not exceed specifications to maintain the stated propagation delay performance.
Part Context
The SN74AUC1G66 series belongs to Texas Instruments' AUC logic family, designed for ultra-low voltage applications. The YZAR variant specifically denotes the DSBGA (YZP) package type. This family is characterized by its ability to handle both AC and DC signals while maintaining low power consumption and high linearity across the specified voltage range.
Replacement Considerations
Direct replacements include other variants of the SN74AUC1G66 series such as SN74AUC1G66DBVR or SN74AUC1G66DCKR, provided the package footprint can be adapted. Verify that any substitute maintains the same NanoFree™ or equivalent small-package characteristics and electrical parameters.
