DM74LS93N, DM74LS90 Datasheet - Fairchild Semiconductor

DM74LS93N Decade and Binary Counters

Each of these monolithic counters contains four master-slave flip-flops and additional gating to provide a divide-by-two counter and a three-stage binary counter for which the count cycle length is divide-by-five for the ’LS90 and divide-by-eight for the ’LS93. All of these counters have a gated zer.
