SN74AUC125RGYRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC125RGYRG4 is a quadruple bus buffer gate with 3-state outputs designed for 0.8-V to 2.7-V VCC operation, optimized for 1.6-V to 1.95-V supply voltages. It features four independent line drivers where each output is disabled when the associated OE input is high. The device supports mixed-mode signal operation as it is 3.6-V I/O tolerant while operating at lower voltages. It includes Ioff circuitry to support partial-power-down mode, preventing damaging backflow current when powered down.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Optimized for sub-1-V operability and low power consumption
• Supports mixed-mode signal operation via 3.6-V I/O tolerance
• Includes Ioff circuitry for partial-power-down applications

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal level translation between different voltage domains
• Partial-power-down mode operations requiring output disabling
• Low-voltage bus buffering in portable electronic devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix RG4 confirms RoHS compliance and green manufacturing status. Confirm the package type RGY corresponds to the 14-pin VQFN configuration. Ensure the operating temperature range matches the application requirements of -40°C to 85°C. Check for any specific moisture sensitivity level (MSL) ratings relevant to the assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation below 1.8 V with high-speed performance. The device is suitable for applications needing 3-state outputs to manage bus lines effectively. Consider its 3.6-V I/O tolerance if interfacing with higher voltage logic levels without additional level shifters.
