When connected as a bi-qui- nary counter, the separate divide-by-two circuit can be � Typical maximum count frequency...35 MHz used to provide symmetry (a square wave) at the final out- � Buffered outputs reduce possibility of collector commu- put stage. The DM74LS390 has parallel outputs from each tation counter stage so that any submultiple of the input count fre- quency is available for system-timing signals.
