Decade and 4-Bit Binary Counters

The SN54290/SN74290, SN54LS290/SN74LS290, SN54293/SN74293, and SN54LS293/

SN74LS293 counters are electrically and functionally identical to the SN5490A/SN7490A,

SN54LS90/SN74LS90, SN5493A/SN7493A, and SN54LS93/SN74LS93, respectively. Only the

arrangement of the terminals has been changed for the ‘290, ‘LS290, ‘293, and ‘LS293.

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 ‘290 and ‘LS290 and divide-by-eight for the ‘293 and ‘LS293. All of these

counters have a gated zero reset and the ‘290 and ‘LS290 also have gated set-to-nine inputs for use

in BCD nine’s complement applications.
