Working Principles
The 74ACT163PC operates based on synchronous counting principles. When the clock signal (CLK) transitions from low to high, the counter increments its value by one. The counter can be preset by applying the desired binary value to the parallel load inputs (LOAD, D0-D3). As the counter reaches its maximum value, the TC (Terminal Count) output generates a carry signal. The counter can be cleared to zero by applying a low signal to the CLR (Clear) input.
Detailed Application Field Plans
The 74ACT163PC finds applications in various digital systems and devices, including but not limited to: - Digital frequency dividers - Time delay circuits - Event counters - Industrial automation systems - Communication equipment - Automotive electronics
