Hi Team,
Do we have solution to replace TC7SET14FU?

Hi SHH,

This is a standard Schmitt-trigger inverter in Toshiba's equivalent for our DCK package (5 pin, 0.65mm pitch) that operates only from 4.5 to 5.5V.

A quick look on the parametrics table yields the only reasonable replacement part:

www.ti.com --> Logic --> Little Logic --> Products --> Gate Type: SCHMITT TRIGGER INVERTER --> VCC (Max) (V): >= 5.5V

The filtered table has two parts - one is a dual Schmitt-Trigger Inverter and the other is the single Schmitt-Trigger Inverter that you are looking for:

SN74LVC1G14-Q1

LVC does not have TTL-compatible inputs, and has faster (i.e., noisier) edges.

Why the Automotive filter?

Toshiba's SET is the equivalent of AHCT1G, so the direct replacement is SN74AHCT1G14‍DCK.

Hi Emrys,
Thansk for teaching for how to choose. It helps!

Could I confirm with you that I use the same selection and the tool show more options?
There are 5 option for the schmitt trigger inverter. Is there any spec that need to choose SN74LVC1G14-Q1?

Thanks,
SHH

You need to add package Group: SC70, and Special Features: TTL compliant.

The part they showed is AEC-Q100 compliant, so an automotive rating is required for a direct replacement. You're right that our part isn't a perfect match, but it's the only one that's close.

I left off the Automotive filter -- under Rating.

If TTL compatibility were not required, the TC7SH14FU (=SN74AHC1G14) would have been used instead.
But Toshiba has no alternative without AEC-Q100, so it's possible that this feature is not required. (And that "For detail information, please contact to our sales" remark implies that it isn't the default.)

Assuming no AEC-Q100, the only possible replacement is the AHCT part.
With AEC-Q100, there is no replacement.
