SN74LV4053A: Revision History

Yuta Nishie

Part Number: SN74LV4053A
Other Parts Discussed in Thread: SN74LV4051A

Tool/software:

Hi,

■In Rev.L of the datasheet, the following items have been changed in addition to the contents of Revision History. Do you plan to add these changes to Revision History?

<Changed Specs>

・P5, VCC（min）

・P6, ICC（Typ）＠25℃ add

・P7, COS, CIS, COS(On)

・P7～P8, Timing Characteristics(Typ)

・P8, tPHZ, tPLZ(max)@VCC=5V±0.5V

・P8, Frequency response (switch on)

■Regarding COS, CIS, and COS (On) of P7, the values are different between Rev.K and Rev.L.

Am I correct in understanding that the measurement conditions are the same, but the values have been changed?

Best Regards,

Nishie

    Hello Nishie,

    Thank you for bringing this to our intention as this could be a datasheet error and we will work to fix this.

    Please expect a response tomorrow to confirm your inquiry about the measurement conditions vs the value changes for some of the specs

    Regards,

    Kameron

    Hello Nishie,

    After further investigation, I will need more time to find out the reason why there are changes between Rev K and Rev L that are not outlined on the rev history. 

    Please let me know if you have any immediate questions regarding this and I will update this thread when I have more information

    Regards,

    Kameron

    Hi Nishie,

    We looked into this, the 23pF number is actually coming from the SN74LV4051A spec, the SN74LV4053A capacitance is still 8.2pF. COS (on) is a new spec that should match CIS. COS did not change, this is simply rounding based on new datasheet standards. 

    Thanks,

    Stephen

    Hi Stephen-san, Kameron-san,

    Thank you for checking.

    I understand that there are changes in the datasheet other than what is described in Revision History. I will pass the information on to the customer. If I receive additional questions from the customer, please let me consult with them.

    Best Regards,

    Nishie
