HD74LS390

Dual Decade Counters

REJ03D0485-0400

Rev.4.00

May 10, 2006

This circuit contains eight master-slave flip-flops and additional gating to implement two individual four-bit counters.

The HD74LS390 incorporates dual divide-by-two and divide-by-five counters, which can be used to implement cycle

lengths equal to any whole and / or cumulative multiples of 2 and / or 5 up to divide-by-100. When connected as a bi-

quinary counter, the separate divide-by-two circuit can be used to provide symmetry (a square wave) at the final output

stage.
