Decade, Divide-By-Twelve 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-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 Q_Aoutput. 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 Q_Doutput to the CKA input and applying

the input count to the CKB input which gives a divide-by-ten square wave at output Q_A.
