DM74LS390
Dual 4-Bit Decade 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
DM74LS390 incorporates dual divide-by-two and divide-
by-five counters, which can be used to implement cycle
lengths equal to any whole and/or cumulative multiples of 2
and/or 5 up to divide-by-100. When connected as a bi-qui-
nary counter, the separate divide-by-two circuit can be
used to provide symmetry (a square wave) at the final out-
put stage. The DM74LS390 has parallel outputs from each
counter stage so that any submultiple of the input count fre-
quency is available for system-timing signals.
Features
s Dual version of the popular DM74LS90
s DM74LS390...individual clocks for A and B flip-flops
provide dual
÷ 2 and ÷ 5 counters
s Direct clear for each 4-bit counter
s Dual 4-bit version can significantly improve system den-
sities by reducing counter package count by 50%
s Typical maximum count frequency...35 MHz
s 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.
