Working Principles

M74HC393TTR operates based on the principles of digital logic circuits. The clock inputs (CLKA and CLKB) control the counting process, while the data inputs (D0-D3) determine the initial count value. The counter increments by one for each rising edge of the clock signal. When the counter reaches its maximum value (15), the carry output (CARRY) is activated. The asynchronous reset input (RST) resets the counter to zero when triggered.

Detailed Application Field Plans

M74HC393TTR finds applications in various digital systems, including but not limited to: - Frequency dividers - Digital clocks - Event counters - Industrial automation - Communication systems - Consumer electronics
