SN74LVC14A: Ioff support

user4109590

Part Number: SN74LVC14A

Hello E2E Logic Forum Members,

Does SN74LVC14A support Ioff ?

I look like SN74LVC14A supports Ioff in the datasheet page.1, but there isn't the Ioff spec into the datasheet page.8 "Electrical Characteristics table".

I understand the octal series (like 245, 374), 1gate, 2gate and 3gate support Ioff, but the gate logic (like 00, 04, 14 and 125) don't support Ioff....

Thanks,

Yasu

Hello Yasu-san,
The SN74LVC14A does _not_ have the Ioff circuitry.

Thank you for finding the error in the front page of the datasheet - I have added it to our list of errata to be fixed.

Emrys-san,

Thanks for your quick reply! I hope the datasheet is updated asap.
Some customer think all LVC devices support Ioff ...

Thanks,
Yasu

An easy rule of thumb is that the LVCxG (1G, 2G, 3G) products will have Ioff, however the LVC family of devices were developed before Ioff technology was available.

Hello Emrys-san

Thanks for teaching the easy rule.

I also told easy rule to our customer as follows,

LVC series which were built by 14pin 16pin package don't have Ioff, but you should confirm whether the device has the Ioff spec in the datasheet.

Thanks
