The 74ACT163SC is an integrated circuit (IC) component that belongs to the 74ACT family of advanced high-speed CMOS devices. It is a synchronous, presettable, 4-bit binary counter which includes internal carry propagation and an overflow output. This IC is widely used in various digital applications that require counting and frequency division functionalities.
One of the key features of the 74ACT163SC is its synchronous operation, which means that the counting and control signals are applied simultaneously. The IC utilizes a common clock input (CLK) that triggers the counting process, ensuring precise timing and synchronization with other circuitry.
Another notable feature of this IC is its preset capability through the Parallel Load (PL) input. By asserting PL to a high logic level, the counter can be loaded with a desired initial value present at the parallel data inputs (P0-P3). This allows for easy initialization and enables the device to be used as a frequency divider by loading a specific count value.
The 74ACT163SC has four individual output pins (Q0-Q3) representing the binary counter states. These pins provide binary values that correspond to the current count of the counter, making it straightforward to interface with other circuits.
Furthermore, the IC incorporates a terminal count output (TC), which indicates an overflow condition when the counter reaches its maximum count value. TC can be used as an interrupt or trigger signal for various control functions
