DM74LS90 DM74LS93 Decade and Binary Counters
General Description
Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the count cycle length is divide-by-five for the ’LS90 and divideby-eight for the ’LS93
All of these counters have a gated zero reset and the LS90 also has gated set-to-nine inputs for use in BCD nine’s complement applications
To use their maximum count length (decade or four bit binary) the B input is connected to the QA output The input
count pulses are applied to input A and the outputs are as descri...
