Overview
The SN74AUC2G66YEPR is a dual bilateral analog switch manufactured by Texas Instruments, belonging to the SN74AUC2G series. It features two independent single-pole single-throw (SPST) channels housed in an 8-pin YZPR package. The device operates on a single supply voltage ranging from 0.8 V to 2.7 V with a maximum quiescent current of 10 µA. Key electrical specifications include a maximum on-resistance of 15 Ohms, a maximum propagation delay of 2.3 ns, and a maximum off-time of 2 ns. It supports a DC switch current of 100 mA and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel configuration providing two independent SPST analog switches for signal routing
- Low on-resistance characteristic ensuring minimal signal attenuation during conduction
- Ultra-low power consumption suitable for battery-operated applications
- High-speed switching capability with nanosecond-level propagation delays
Applications
- Portable consumer electronics requiring low-voltage signal switching
- Battery-powered devices where power efficiency is critical
- Communication equipment utilizing low-voltage logic interfaces
- Automotive infotainment systems operating within specified temperature ranges
Procurement Notes
Verify the specific suffix YEPR against official Texas Instruments documentation to confirm the package type and tape-and-reel configuration. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when designing circuits that require dual analog switching under low-voltage conditions between 0.8 V and 2.7 V. Consider the 15 Ohm on-resistance and 100 mA DC switch current limits relative to the load requirements. Verify that the 8-pin package footprint aligns with the PCB layout constraints and thermal management strategies.
Part Context
This part belongs to the SN74AUC2G family of ultra-low-voltage CMOS analog switches. It shares functional similarities with other members like the SN74AUC2G66DCUR but differs in packaging. The AUC series is designed for high-speed, low-power applications compared to legacy LVC or HCT families.
Replacement Considerations
The SN74AUC2G66DCUR is a functionally equivalent alternative offering identical electrical performance in an 8-VSSOP package. Verify pinout compatibility and physical dimensions before substitution to ensure proper fit within the existing enclosure and PCB design.
