74AUC2G125DCURG4

Overview

The SN74AUC2G125DCURG4 is a dual bus buffer gate manufactured by Texas Instruments, belonging to the AUC logic family. It features two non-inverting buffers with three-state outputs in an SC-70 package. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical parameters include a propagation delay of 1.8 ns at 3.3 V and output drive capabilities of ±24 mA for both high and low states. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent buffering for two signal lines
• Three-state output control allowing multiple drivers on shared buses
• Low-voltage operation optimized for modern portable electronics
• High-speed performance suitable for data-intensive applications

Applications

• Portable equipment requiring low power consumption
• Memory and flash card interfaces
• Consumer products utilizing high-density packaging
• Computing and instrumentation systems

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm RoHS compliance status and lead time requirements. Ensure the SC-70 package dimensions match your PCB footprint constraints. Confirm that the 1.65V to 3.6V operating range aligns with your system's power rails before finalizing procurement.

Selection Notes

Select this component when a dual-buffer solution with three-state capability is required in a minimal footprint. The AUC series offers superior speed compared to standard CMOS while maintaining low static power dissipation. Verify that the input voltage levels are compatible with your source logic family to ensure proper switching thresholds and noise margins during operation.

Part Context

This part belongs to the SN74AUCxx family of ultra-low voltage CMOS logic devices. It serves as a compact alternative to larger packages like SOT-353 or VSSOP for space-constrained designs. The device integrates level-shifting capabilities inherent to the AUC technology, facilitating interface between different voltage domains in mixed-signal environments.

Replacement Considerations

Direct substitutes include the SN74AUC2G125DCUR without the G4 suffix if environmental compliance differs. Other pin-compatible options may exist within the same logic family from Texas Instruments, provided the package type and electrical characteristics remain identical.
