Overview

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.

  • Typical power dissipation - 90A 145 mW - 93A 130 mW
  • Count frequency 42 MHz Connection Diagrams Dual-In-Line Package Dual-In-Line Package
