DECADE COUNTER; 4-BIT BINARY COUNTER

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 tr
