SN74AHC244: SN74AHC244 Vin higher than VCC

Kelvin Kalariya4

Part Number: SN74AHC244

Dear All,

In an application, we need to convert data signal from 5V to 3.3V. By giving 3.3V to VCC will my IC able to receive 5V at I/P buffer and will convert it to 3.3V signal?

Thanks

Hi Kelvin,

That should be fine, as the input voltage is independent of VCC and 3.3 is within the allowed range. You can refer to the FAQ document for details here.

regards,

Gabriel
