DM74LS393
Dual 4-Bit Binary Counter
General Description
Each of these monolithic circuits contains eight master-
slave flip-flops and additional gating to implement two indi-
vidual four-bit counters in a single package. The
DM74LS393 comprises two independent four-bit binary
counters each having a clear and a clock input. N-bit binary
counters can be implemented with each package providing
the capability of divide-by-256. The DM74LS393 has paral-
lel outputs from each counter stage so that any submultiple
of the input count frequency is available for system-timing
signals.
Features
I
Dual version of the popular DM74LS93
I
DM74LS393 dual 4-bit binary counter with individual
clocks
I
Direct clear for each 4-bit counter
I
Dual 4-bit versions can significantly improve system
densities by reducing counter package count by 50%
I
Typical maximum count frequency 35 MHz
I
Buffered outputs reduce possibility of collector commu-
tation
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
