HD74LS161AP (74LS161)
The HD74LS161AP, commonly known as 74LS161, is a synchronous 4-bit binary counter IC (Integrated Circuit). It is designed to count in binary from 0 to 15 and can be cascaded for higher counting applications. The IC operates using synchronous logic, where the outputs change state simultaneously with a clock signal.
Key Features:
- Binary Counter: Counts in binary from 0 to 15 (4-bit counter).
- Synchronous Operation: Outputs change simultaneously with the clock signal.
- Presettable: Can be preset to any initial value using the parallel load (PL) input.
- Cascadable: Multiple ICs can be cascaded for higher counting applications.
- Clock Enable Input: Allows disabling the clock input and the asynchronous reset function.
- Low Power Consumption: Suitable for battery-operated devices.
- Package Type: Available in various package options, including PDIP and SOP.
- Frequency division and counting applications.
- Digital clocks and timers.
- Sequential logic circuits.
- Event counting in microcontroller systems.
- Education and learning projects.
