Max Frequency of a 74AC240 Octal Buffer Chip

[Fischer777]

I am trying to construct an inexpensive inverter for a battery-powered AC experiment. I was planning on using as part of it a 74AC240 buffer chip, however, no matter where I look I cannot seem to find what its maximum operating frequency is. The inverter needs to produce a frequency of several hundred hertz to even a few kilohertz. I'm not sure if that is too much to expect from a simple buffer chip.

If you look on page 6 of this http://www.fairchildsemi.com/ds/74/74AC240.pdf

You will see all the signal delay and propagation times are given in nanoseconds.

Any TTL logic family chip will work OK up to a few MHz, so speeds of a few kHz are not an issue.
