The IC component 54ACT521/Q2A is a high-speed, 8-bit counter with a synchronous reset function. It is primarily used in digital circuit designs where accurate counting and synchronization capabilities are required. This component belongs to the ACT series and is manufactured by numerous semiconductor companies.
Key features of the 54ACT521/Q2A include:
1. 8-bit Counter: The IC component features an 8-bit binary counter, which allows it to count up to 255 (from 0 to 255) in binary format. The counter can be incremented by applying clock pulses to the appropriate input pins.
2. Synchronous Operation: The counting operation of the 54ACT521/Q2A is synchronous, meaning the counter updates its value simultaneously with the provided clock signal. This feature ensures precise timing and synchronization within the system.
3. Reset Function: The IC component comes with a synchronous reset input pin that allows the counter to be reset to zero instantly. When a HIGH signal is applied to the reset input, the counter resets to 00000000, irrespective of its current count. This enables easy initialization of the counter.
4. Clock Enable and Disable: The 54ACT521/Q2A provides a clock enable and disable feature that allows controlling the clock signal's accessibility to the counter. By setting the clock enable input low, the clock signal is inhibited, freezing the counter's state
