FEATURES
Two 4-bit binary counters
Two Master Resets to clear each 4-bit counter individually
DESCRIPTION
The 74F393 is a Dual Ripple Counter with separate Clock (CP
n
) and
Master Reset (MR) inputs to each counter. The two counters are
identified by the "a" and "b" suffixes in the pin configuration. The
operation of each half of the 74F393 is the same. The counters are
triggered by a High-to-Low transition of the Clock (CP
a
and CP
b
)
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 (MR
a
and MR
b
) are active
High asynchronous inputs; one for each 4-bit counter. A High level
in the MR input overrides the Clock and sets the outputs Low.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
CC
= 5V, T
amb
= 25
C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
