FUNCTIONAL DESCRIPTION
Each half of the SN74LS393 operates in the Modulo 16
binary sequence, as indicated in the ÷16 Truth Table. The
first flip-flop is triggered by HIGH-to-LOW transitions of
the CP input signal. Each of the other flip-flops is triggered
by a HIGH-to-LOW transition of the Q output of the
preceding flip-flop. Thus state changes of the Q outputs do
not occur simultaneously. This means that logic signals
derived from combinations of these outputs will be subject
to decoding spikes and, therefore, should not be used as
clocks for other counters, registers or flip-flops. A HIGH
signal on MR forces all outputs to the LOW state and
prevents counting.
