DESCRIPTION
The 74LV393 is a low–voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT393.
The 74LV393 is a dual 4-bit binary ripple counter with separate
clocks (1CP, 2CP) and master reset (1MR, 2MR) inputs to each
counter.
The operation of each half of the ‘‘393’’ is the same as the ‘‘93’’
except no external clock connections are required. The counters are
triggered by a HIGH-to-LOW transition of the clock inputs. The
counter outputs are internally connected to provide clock inputs to
succeeding stages. The outputs of the ripple counter do not change
synchronously and should not be used for high-speed address
decoding.
The master resets are active-HIGH asynchronous inputs to each
4-bit counter identified by the ‘‘1’’ and ‘‘2’’ in the pin description.
A HIGH level on the nMR input overrides the clock and sets the
outputs LOW.
