Overview
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 section 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).
