SN74AUC1G17YEAR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G17YEAR is a discontinued single Schmitt-trigger buffer from Texas Instruments, part of the AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V and features push-pull outputs with a maximum propagation delay of 2.4 ns at 1.8 V. The device provides latch-up protection exceeding 100 mA per JESD 78 Class II standards and includes Ioff circuitry for partial power-down support. It is housed in a 5-pin DSBGA package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals.
• Ioff circuitry disables outputs to prevent damaging current backflow during partial power-down states.
• Inputs are tolerant up to 3.6 V, supporting mixed-mode signal operation despite lower supply voltages.

Buffers, Drivers, Receivers, Transceivers Applications

• AV Receiver
• Portable Audio Dock
• Blu-Ray Player and Home Theater
• Embedded PC
• Solid State Drive (SSD)

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component status before procurement as this specific variant is marked as obsolete and no longer manufactured. Confirm availability of parameter-equivalent active replacements such as the SN74AUC1G17YZPR. Ensure design files and datasheets reference the correct revision history to account for any historical specification updates prior to discontinuation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component only if legacy compatibility or specific board layout constraints require the YEAR suffix designation. For new designs, evaluate active alternatives within the SN74AUC1G17 product folder that offer identical electrical characteristics and pinout configurations. Verify that the NanoFree packaging technology meets the mechanical requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AUC1G17 product line, which consists of single-channel buffers designed for high-speed digital applications. The AUC series focuses on sub-1-V operability and low power consumption. The YEAR suffix indicates a specific manufacturing lot or tape-and-reel configuration associated with the DSBGA package type.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74AUC1G17YZPR is documented as a parameter-equivalent replacement for the discontinued SN74AUC1G17YEAR. Both parts share the same logical function and electrical specifications but may differ in specific packaging markings or manufacturing dates.
