74F393Dual 4-bit binary ripple counter
FEA TURES
•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 (CPn) 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
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
and MRb) are active
a
High asynchronous inputs; one for each 4-bit counter. A High level
in the MR input overrides the Clock and sets the outputs Low.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
