  • Manufacturer: Harris Semiconductor

    Short Description

    Dual 4 -Stage Binary Counters.

    General Description

    The Harris CD74HC393 and CD74HCT393 are 4-stage ripple-carry binary counters. Al counter stages are master- slave flip-flops. The state of the stage advances one count on the negative transition of each clock pulse; a high voltage level on the MR line resets all counters to their zero state. All inputs and outputs are buffered.

    Features

    1. Fully Static Operation.</br> 2. Buffered Inputs.</br> 3. Common Reset.</br> 4. Negative-Edge Clocking.</br>
