Square wave frequency to binary conversion question.

Hello everyone..
Is there any IC known out there or a circuit that would convert square wave signal to binary?
Range would be from 100 Hz to 1 kHz (possibly up to 10 kHz).
Looking for circuit without microcontroller involved.

Thanks in advance,

By square wave, do you mean series of square pulses?
Meaning that you are not actually sending square wave, because square wave has half of wave period low and half of wave period high. If you send two square pulses in a row that are high, then half the period is high and other half the period is also high.
