Greetings All.

I'm sorry for such a stupid question but I've no datasheets
around for this moment. I'm trying to find pin to pin compa-
tible analog for TTLSh invertor 74ALS04 within 74HC or 74HCT
HCMOS families. Is it possible on the whole ? Should I look
for another substitution for ALS family to another TTLS's ?

Thank you in advance.

WBR Dmitry.
