The datasheet for SN74LVC1G17 said at 3.3V voltage, the highest speed application up to 100M.
Question: When supply voltage is 1.8V, what are the highest frequency for signal conditioning and level shift? the frequency for signal conditioning and level shift the same or different?
Hi Xing,
The maximum speed of most logic gates isn't specified - ie we don't guarantee a maximum operating frequency.
There's a plot in the applications section of this datasheet that shows 1.8-V operation up to 75 MHz (via power consumption graph), however it does not show signal integrity or load conditions for that test.
We recommend using a similar device (same logic family) that _does_ have a specified clock frequency to estimate the maximum operating frequency of a single logic gate. For this device, the SN74LVC1G79 is a good comparison, with a maximum rated clock frequency of 160 MHz at 1.8V.
