SN74AUC17RGYRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC17RGYRG4 is a hex Schmitt-trigger buffer from the Texas Instruments AUC logic family, housed in a 14-pin VQFN package. It operates within a supply voltage range of 0.8 V to 2.7 V and features six independent non-inverting buffers with distinct positive-going (VT+) and negative-going (VT-) input threshold levels. The device supports partial-power-down mode via Ioff circuitry, which disables outputs to prevent backflow current. It provides ±8-mA output drive at 1.8 V and exhibits a maximum propagation delay of 1.8 ns at 1.8 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Hex Schmitt-trigger buffer configuration for noise-immune signal conditioning
• Ioff circuitry enables partial-power-down operation to prevent damaging backflow currents
• Optimized for 1.8-V operation while maintaining 3.6-V I/O tolerance for mixed-mode systems

Buffers, Drivers, Receivers, Transceivers Applications

• Partial-power-down applications requiring output disabling during power-off states
• Mixed-mode signal processing interfaces between different voltage domains
• Signal buffering where noise immunity against slow or noisy input transitions is required

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm that the RGY package designation matches the required 14-pin VQFN footprint and thermal characteristics for your PCB layout. Ensure compatibility with the specified -40°C to 85°C operating temperature range for your intended environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing low-voltage digital circuits requiring hysteresis for clean signal regeneration. The AUC series offers lower power consumption compared to legacy families. Consider the 14-pin VQFN package constraints regarding thermal dissipation and soldering profiles. Verify that the 0.8-V minimum supply voltage aligns with your system's power rails.
