Part Number: SN74AHC245
Other Parts Discussed in Thread: SN74AHC74
Hi team,
Can you provide the recommended max BW of SN74AHC245?
Or can you provide me the related calculation that you could calculate the max BW? I think it's related to tr and tf.

Hi Roy,
We have an FAQ on this topic here: (+) [FAQ] What is the maximum data rate (or operating frequency) for a logic gate or buffer? - Logic forum - Logic - TI E2E support forums
For the AHC245 operating at 5V, I would expect it to work up to 110 MHz with a light load (15 pF) or up to 75 MHz with a relatively heavy load (50 pF).
This comes from the SN74AHC74 datasheet:
