Working Principles

The CD74HCT393MT is a ripple counter that counts binary numbers. It consists of two separate 4-bit counters, each with its own clock input. The counters increment on the rising edge of the clock signal. An asynchronous reset input allows the counters to be cleared to zero.

The outputs of the counters are available in both normal and complementary forms. This provides flexibility in connecting the counters to other digital logic circuits. The wide supply voltage range allows the CD74HCT393MT to be used in various systems.
