SN74LVC2T45: current consumption when Vi> Vcci

SYLVAIN BOURIOT

Part Number: SN74LVC2T45

Tool/software:

Hello,

Unlike other 74LVCxx products, SN74LVC2T45 current consumption is only is specifified when VI=Vcci or GND but not when Vi=5.5V.

Do you have any information on this subject?

Best Regards.

Hi Sylvain,

Unfortunately, it is not specified as data was not collected.

Note that Vi > Vcci is of no concerns as concern is typically for when Vi < Vcci where VIH/VIL threshold will not be valid for a valid logic level. Hence, the additional current consumption specified as 50 uA. Please see [FAQ] Can the input voltage (Vi) to my logic device be higher than the supply voltage (Vcc)? for more information, thanks.

Best Regards,

Michael.

Hi Mickael,

Thanks, I've already read the link you mentioned.
