DIVIDE-BY-TWELVE COUNTER

DESCRIPTION- The ’92 is a 4-stage ripple counter containing a high speed flip-flop acting as a divide-by-two and three flip-flops connected as a divide-by-six. HIGH signals on the Master Reset (MR) inputs override the clocks and force all outputs to the LOW state.

The SN54/74LS90, SN54/74LS92 and SN54/74LS93 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 (LS90), divide-by-six (LS92) or divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transition
