Hi team,
In the datasheet, it says
"The device can produce 24 mA of drive current at 3.3 V, which is ideal for driving multiple outputs and good for high-speed applications up to 100 MHz"
I guess this means that when Vcc=3.3V, maximum signal speed is 100MHz and the device can drive 24mA in that condition, right?
Also, how about when Vcc=1.2V? What is the signal speed limitation for Vcc=1.2V?

This paragraph was copied from the SN74LVC1G125 datasheet, but the values are wrong. AUP devices can drive 4 mA at 3.3 V, the maximum frequency is 160 MHz.
At 1.2 V, the drive strength is 1.1 mA, and the maximum frequency is 40 MHz.
Hi Ladisch
I was meant to post this question to SN74LVC1G125, sorry for the mistake.
How about LVC device??
At 3.3 V, LVC devices support 175 MHz.
At 1.2 V, LVC devices are not guaranteed to work.
Hi Ladisch,
I read the datasheet for SN74AUP1G125 and it actually says
"The device can produce 24 mA of drive current at 3.3 V, which is ideal for driving multiple outputs and good for high-speed applications up to 100 MHz"
Could you again answer to my question
What is the driving strength and maximum frequency for Vcc=3.3V and Vcc=1.2V for SN74AUP1G125?

Ohashi
At 3.3 V, AUP devices can drive 4 mA, and support 160 MHz.
At 1.2 V, AUP devices can drive 1.1 mA and support 40 MHz.
Hi Ladisch,
So you meen that the datasheet for SN74AUP1G125 has a typo?

Hi Ladisch,
Thanks for the reply.
Now I'm clear.
Will you guys gonna update the datasheet since it's telling the wrong value?

I am not a TI employee. But I've submitted feedback with the link in the datasheet.
