DECADE COUNTER;

4-BIT BINARY COUNTER

The SN54 / 74LS290 and SN54 / 74LS293 are high-speed 4-bit ripple type

counters partitioned into two sections. Each counter has a divide-by-two sec-

tion and either a divide-by-five (LS290) or divide-by-eight (LS293) section

which are triggered by a HIGH-to-LOW transition on the clock inputs. Each

section can be used separately or tied together (Q to CP)to form BCD,

Bi-quinary, or Modulo-16 counters. Both of the counters have a 2-input gated

Master Reset (Clear), and the LS290 also has a 2-input gated Master Set

(Preset 9).
