Divide-By-Twelve Decade Counter

Each of these monolithic Counters SN74LS92 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 '90A and 'LS90, divide-by-six for the '92A and 'LS92, and the divide-by eight for the '93A and 'LS93.
All of these Counters have a gated zero reset and the '90A and 'LS90 also have gated set-to-nine inputs for use in BCD nine's complement applications.
To use their maximum count length (decade, divide-by-twelve, or four-bit binary) of these Counters the CKB input is connected to the QA output. The input count pulses are applied to CKA input and the outputs are as described in the appropriate function table. A symmetrical divide-by-ten count CAN be obtained from the '90A or 'LS90 Counters by connecting the QD output to the CKA input and applying the input count to the CKB input which gives a divide-by-ten square wave at output QA.
