4-Bit Binary Counter

General Description\nThe ’LS293 counter is electrically and functionally identical to the ’LS93. Only the arrangement of the terminals has been changed for the ’LS293.\nEach of these monolithic counters contains four master slave flip-flops and additional gating to provide a divide-by two counter an ■ GND and VCC on Corner Pins (Pins 7 and 14 respectively)\n■ Typical power dissipation 45 mW\n■ Count frequency 42 MHz;

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
