When lv07a output is turned on, I expect the voltage lvc0a7 be close to 0, and current to be about uA 8V through 10K resistor. When the output is turned off, the voltage will presumably be close to 8V, but very little current will be flowing.
74LVC07APW – Hex buffer with open-drain outputs | Nexperia
At first glance, the current should always be well below the 50mA max output current spec, so I would expect this configuration to be fine. I sent this question to NXP tech support 3 days ago, and haven’t heard from them yet. Maybe someone on this forum can give me a definitive answer so I can proceed with the design. You’re kind of in a gray area.
The output should not break down until you get to more than 6. Remember that “limiting values” aka “absolute maximum” are not intended to indicate where the part should be operated continuously for reliable operation. The recommended maximum output voltage for normal operation is less than 5.
Ignore that at your peril- only you know what the consequences of a failure are. It’s also better to drive the inputs right to the rails otherwise the current draw of the could go up.
That’s what I suggest doing. This was the response:.
Using the 74LVC07A is one of the more common ways to interface 3. The note in the LVC07A datasheet “The output voltage ratings may be exceeded if the output current ratings are observed” allows you to let the output be pulled higher than the suggested limit of 6.
Your uA should be no issue in fact, you may want to reduce that 10K resistor if you need to improve the rise time of the output signal.
I find it interesting that he refers to the Absolute Maximum Rating as a “suggested limit. Since this answer lvvc07a from the device manufacturer, I will mark it as being the correct answer.
Since Daatasheet eventually received a reply to my inquiry from NXP Support, and they responded that my original approach was permissible, I have posted their response and I expect to mark it as the correct answer. Good that you got something in writing. I find “should be no issue” somewhat different from “is definitely no problem” though. This was the response: Your uA should be no issue in fact, you may want to reduce that 10K resistor if you need to improve the rise time of the output signal Regards Tom Logic Applications Engineering I find it interesting that he refers to the Absolute Maximum Rating as datashret “suggested limit.
