7493 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
described in the appropriate truth table. A symmetrical divide-by-ten count can be obtained from the 90A counters by connec
