74F393

Dual 4-bit binary ripple counter

2

1988 Nov 01

853–0295 94977

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 (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 (CPa and CPb)

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 (MRa and MRb) 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.
