Overview

DM7490A, DM7493A Decade and Binary Counters March 1998 DM7490A, DM7493A 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 90A and divide-by-eight for the 93A.
All of these counters have a gated zero reset and the 90A 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 descr...
