Overview

DM74LS90/DM74LS93 Decade and Binary Counters March 1998 DM74LS90/DM74LS93 Decade and Binary Counters General Description 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 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 a...
