74LS93 High Speed 4-bit ripple type Binary Counter
The 74LS93 is high-speed 4-bit ripple type counters partitioned into two sections. Each counter has a divide-by-two section and either a divide-by-eight (LS93) 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, modulo-12, or modulo-16 counters. The counter have a 2-input gated Master Reset (Clear), and the LS90 also has a 2-input gated Master Set (Preset 9).
