SN74AVC4T245: OE threshould

Hideki Hayashi1

Part Number: SN74AVC4T245

Hi team,

I undertand OE is referenced to Vcca and it has tolerance to 3.6V even Vcca is 1.8V. By the way, what is the threshold voltage of high and low?

Best regards

Hayashi

Hi Hyashi,

Since referenced to VCCA, it would be for 1.8 V high and low in this case, thanks.

Best Regards,

Michael.

Hi Michael,

My question is high threshold and low threshold such as Vcca*0.70 and Vcca*0.35 or so on. how much is the threshold voltage?

Hi Michael,

Do you mean OE spec is completely same as DIR? If so, that's clear. But please add that on the datasheet

Hayashi

Hi Hayashi,

Yes, you may use DIR spec as they are both inputs that enable and disables the outputs, thanks.

Best Regards,

Michael.
