SN74AUC17RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC17RGYR is a hex Schmitt-trigger buffer manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.8-V operation with 3.6-V I/O tolerance. The device contains six independent buffers providing non-inverting Boolean logic (Y = A). It features a maximum propagation delay of 1.8 ns at 1.8 V and supports partial-power-down mode via the Ioff circuitry. The component is housed in a 14-pin VQFN package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Incorporates Schmitt-trigger action to provide distinct positive-going and negative-going input threshold voltages for noise immunity.
• Includes dedicated Ioff circuitry that disables outputs to prevent damaging current backflow during partial-power-down applications.
• Designed specifically for mixed-mode signal environments, allowing compatibility between sub-1-V devices and 3.6-V I/O systems.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial-power-down mode operations requiring output isolation
• Mixed-mode signal processing between different voltage domains
• Signal buffering where noise immunity is required

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix RGYR corresponds to the VQFN-14 package and tape-and-reel carrier configuration. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the supplier provides documentation matching the manufacturer's standard packaging specifications for this part number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring six independent non-inverting buffers with hysteresis characteristics. It is suitable for low-voltage applications operating between 0.8 V and 2.7 V. Consider the Ioff feature if the design requires protection against backflow currents during power-down states.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AUC series of advanced ultra-low-power CMOS logic components. The AUC family is characterized by operation at supply voltages below 2.7 V, offering reduced power consumption compared to standard logic families while maintaining high-speed performance suitable for portable electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official substitution guides for equivalent hex Schmitt-trigger buffers within the same voltage range. Verify pinout compatibility and electrical specifications before replacing the component with alternative manufacturers' parts.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function in this device?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current from flowing back through the device into the power supply lines.

What is the purpose of the Schmitt-trigger inputs?

The Schmitt-trigger action provides different input threshold levels for positive-going and negative-going signals, which improves noise immunity on the input lines.
