SN74LVC2G126: About switching speed spec

Tsukui Yusuke
Guru 21930 points
Part Number: SN74LVC2G126


Hi,

Could you tell me about SN74LVC2G126 switching speed spec?
Web page has the following description.



However, its spec is not described in the data sheet.
The customer wants to know the maximum frequency in VCC=1.8V condition.
Could you give me your advice?

Best Regards,
Yusuke

    Hello Yusuke-san,

    The "nominal" voltage for the LVC family is 3.3 V.

    While we do not specify or characterize switching speed non-clocked logic devices, we do provide an expected maximum operating frequency to help customers understand the general limitations of logic devices.

    My recommendation would be to get the part and test at their desired operating frequency in their desired operating environment.  At high speeds, there are too many factors to consider to just sum it up with a single number.

    There's some more information on where this number comes from located here: [FAQ] What is the maximum data rate (or operating frequency) for a logic gate or buffer?
