SN74AUC125RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC125RGYR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V, optimized for 1.8-V operation and featuring 3.6-V I/O tolerance for mixed-mode signal support. The device contains four independent line drivers where each output disables when the associated OE input is high. It supports partial-power-down mode via Ioff circuitry to prevent backflow current. Key electrical parameters include a maximum propagation delay (tpd) of 2.1 ns at 1.8 V, ±8-mA output drive capability at 1.8 V, and a maximum ICC of 10 μA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Optimized for 1.8-V operation with 3.6-V I/O tolerance to support mixed-mode signal environments
• Ioff circuitry enables partial-power-down mode to prevent damaging current backflow during power loss
• High ESD protection performance exceeding JESD standards for human-body, machine, and charged-device models

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal applications requiring level translation between low-voltage logic and 3.6-V interfaces
• Partial-power-down systems utilizing Ioff functionality to isolate powered-down components
• High-speed data buffering in portable or battery-operated electronic devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix RGYR corresponds to the 14-pin VQFN package with tape-and-reel packaging containing 3000 units per reel. Confirm that the RoHS compliance status and lead finish (NIPDAU) match project requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target application before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring low-power buffering with sub-1-V operability and fast switching speeds. The device is suitable for applications needing 3-state outputs controlled by active-low enable signals. Consider its 3.6-V tolerant inputs if interfacing with higher voltage domains while maintaining a lower core supply voltage. Verify that the required output drive current does not exceed the specified limits at the chosen operating voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUC series of ultra-low-voltage CMOS logic devices from Texas Instruments. The AUC family is characterized by operation below 2.0 V, offering reduced power consumption compared to standard 5-V or 3.3-V logic families. The SN74AUC125 specifically provides quad buffering functionality, distinguishing it from other members like the SN74AUC1G125 which offers single-channel buffering in a smaller package.
