If there is data of the leakage current of SN74LS38, please let me know.

Moreover, if there is a related graph of leakage current and temperature characteristics, please let me know together.

Thank you for your consideration.

Is it difficult to take out too the spec. which is not written to the data sheet?

Isn't there such any data?

Since it will answer "There is nothing" if there is nothing, please answer.

Hi Satoshi

II, IIH, ans IIL specd on page 3 of the datasheet are the worst case leakage across voltage, temp and process. I could not lacate any typical values or charts.

Dear Chris-san

Thank you for the advice.

Although II, IIH, and IIL think the leakage current by the side of an input, is there any data of the leakage current　by the side of an output　(IOZ:off-leak output current) ?

※The value of the leakage current which flows into OUTPUT"Y" when OUTPUT"Y" is OFF (by data sheet 2-page)

Best regards,

Satoshi

This part actually has an IoH spec of .25 ma. That is how much it could leak on the output if the output is high impedance.

The custoemr might consider using a more modern part for less leakage like the SN74LVC1G38.
