SN74LS290 DECADE COUNTER

The LS290 and LS293 are 4-bit ripple type Decade, and 4-Bit Binary counters respectively. Each device consists of four master/ slave flip-flops which are internally connected to provide a divide-by-two section and a divide-by-five (LS290) or divide-by-eight (LS293) section. Each section has a separa.
SN74LS290 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.
