Part Number: SN74LVCH32373A

Dear Sir,

I'm FAE in Arrow Korea.

I'll design this part to customer's new project.

Our customer wants to know operating and standby current value individually, including test condition.

Pls, let me know after check it.

Best regards,

Michael

Dear Sir,

Our customer is not able to calculate it by your guide.

I want to get information about operating and standby current value individually, including test condition of SN74LVCH32373A.

Could you pls give me your answer?

Best Regards,

Michael

What exactly is the problem? The datasheet lists I_CC ≤ 40 µA and C_pd ≈ 39 pF.

Dear Sir,

I have a another question.

Our customer wants to control all OE pin(total OE pins = 12pins) of SN74LVCH32373A 3pcs by single GPIO(only one) of MCU.

If they configure like above, how many current have to be guaranteed at GPIO of MCU?

Also, Could you please send me If you have any reference circuit?

As your reference, I attached system block diagram.

Best regards,

Michael

12 × I_I = 12 × 5 µA = 60 µA
