SN74AUP1T34: How to define the Max working frequency?

Penn Zhang

Part Number: SN74AUP1T34

Hi team,

I searched all over the datasheet, can't find somthing about the maximam working frequecy, only the delay and a curve shows working under10Mhz.

normally, these kind of product how to know what's the max working frequency.

Thank you.

How to Select Little Logic shows the official frequencies for single-supply gates:

As a safe estimate, you can use the propagation delay time as the maximum time needed to transmit a single bit. For example, translating from 1.8 V to 3.3 V with a load of 5 pF has a maximum t_pd of 7.88 ns, so the estimated maximum data rate would be 126.9 Mbps, or a frequency of 63.4 MHz. (The real rate is somewhat higher than this estimate because the input voltage is allowed to change some time before the output has finished switching.)
