SN74AUC07RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC07RGYR is a hex buffer/driver with open-drain outputs from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.8-V operation while remaining 3.6-V I/O tolerant. The device features a maximum propagation delay of 2.2 ns at 1.8 V, low power consumption with a maximum quiescent current of 10 μA, and ±8-mA output drive capability at 1.8 V. It is housed in a 14-pin VQFN package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Open-drain outputs enable active-low wired-OR or active-high wired-AND configurations.
• Supports partial-power-down mode via integrated Ioff circuitry to prevent backflow currents.
• Designed specifically for mixed-mode signal operation between 1.8-V and 3.6-V domains.

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-signal level translation between 1.8-V and 3.6-V systems
• Implementing wired-logic functions on shared bus lines
• Partial-power-down applications requiring output isolation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the moisture sensitivity level and reflow temperature ratings align with your assembly process requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when open-drain outputs are necessary for wired-logic implementation or level shifting. It is suitable for designs requiring sub-1-V operability combined with 3.6-V tolerance. Consider the 14-pin VQFN footprint constraints and ensure unused inputs are tied to defined logic levels to maintain stability.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUC series of high-speed CMOS logic devices. The AUC family focuses on low-voltage operation and reduced power consumption compared to standard 5-V logic families. The RG Y suffix indicates a quad flatpack no-lead (VQFN) surface-mount package designed for compact PCB layouts.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the outputs be connected directly together?

Yes, because the outputs are open-drain, they can be connected to implement active-low wired-OR or active-high wired-AND functions.

How does the device handle partial-power-down scenarios?

The integrated Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device.
