Hi,

I'm wanting divide BCK on TDA1541A with 74HC4040 as outlined here;

I can get either 74HC4040N or CD74HC4040E, Clock frequencies are 98MHz and 35MHz respectively - which is the correct IC for the application?

Many Thanks,
Shane

The clock frequency on the respective data sheets is simply stated being either 98MHz or 35MHz.

this link should work, top two chips on the page - scroll down an inch.

Thanks,

Found the data sheet which says 'Max.' Clock Frequency.

22.5792Mhz is what I have for 44.1Hz.

35MHz or 98MHz - is this to say that they would work equally well, with no difference when being fed 22.5792MHz?
