Overview
The SN74AUC2G66YZPR is a dual bilateral analog switch manufactured by Texas Instruments, designed for low-voltage signal routing applications. It operates within a supply voltage range of 800 mV to 2.7 V and supports single-supply configurations. The device features two independent SPST channels with a maximum on-resistance of 15 Ohms and a DC switch current capability of 100 mA. Key performance metrics include a maximum propagation delay of 2.3 ns and an off-time of 2 ns. It functions reliably across an extended temperature range from -40°C to +85°C. Housed in an 8-DSBGA package, it draws a maximum supply current of 10 uA.
Feature Summary
- Supports low-voltage operation starting at 800 mV for compatibility with modern portable electronics.
- Provides high-speed signal switching with minimal propagation delay for data integrity.
- Features bilateral conductivity allowing signals to pass in either direction through the channel.
Applications
- Portable consumer electronics requiring efficient power management and signal routing.
- Battery-powered devices utilizing low-voltage logic families.
- Data acquisition systems needing isolated analog signal paths.
Procurement Notes
Verify the specific ordering suffix YZPR to confirm the DSBGA-8 package type and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate authenticity and revision status before procurement.
Selection Notes
Select this component when a dual-channel analog switch is required for sub-3V logic systems. Compare the 15 Ohm on-resistance against circuit impedance requirements to ensure acceptable signal attenuation. Consider the 8-DSBGA footprint constraints during PCB layout planning. Verify that the 100 mA switch current rating exceeds the maximum load current expected in the application.
Part Context
This device belongs to the SN74AUC2G66 series of analog switches. It shares functional similarities with other members like the SN74AUC2G66DCUR but differs in physical packaging. The series is characterized by ultra-low voltage operation and high speed, distinguishing it from standard 5V tolerant logic switches.
Replacement Considerations
The SN74AUC2G66DCUR serves as a direct functional alternative with identical electrical specifications. It utilizes a VSSOP-8 package instead of DSBGA-8, requiring mechanical adaptation during replacement. No other substitutes are confirmed in the provided source material.
