DS3658: Datasheet clarification

Part Number: DS3658

Team, 

My customer needs the following clarification.  Any light/background you can shed would be much appreciated.   

We are awaiting delivery of some parts, the TI DS3658, I believe from a distributor.  The delivery is being held up because the datasheet currently says that I-input-high is 1 uA max.  Our spec says the max current is 10uA.

Digging through old datasheets, I found that when it was a National Semi datasheet, the Input High max current was 10 uA, but as soon as it changed to a TI datasheet, the max

value changed to 1uA.  Another oddity is that the "typical" value on both datasheets is 1uA.  It seems odd that the Max value would be the same as the Typical value, doesn't it? 

 Is there a way you can check this?  I have a feeling that maybe the value was just transcribed to the new datasheet incorrectly.

Regards,

Aaron

  • Hey Aaron, 

    Long time no see, I hope everything is going well! 

    This being an older device, (released in 1995), it will take some time to dig through the archives to see what the value is. My initial assumption is that the customer is correct, it wouldn't make sense that the typical and the max value would be the same.

    Let me get back to you on this.

    Thanks,

    Arthur Huang

  • Hey Aaron,

    After talking to our design team, we found this to be a datasheet typo. We will work to update the datasheet value.

    Thanks!
