The SNJ54HC161J is an integrated circuit (IC) component that belongs to the SNx4HC series of high-speed CMOS logic. It is a synchronous presettable 4-bit binary counter with an asynchronous reset and parallel load capability. Here is an overview of its key features:
1. High-Speed Operation:
- The SNJ54HC161J is designed for high-frequency applications, with a typical propagation delay of 13ns.
- It operates at a wide voltage range of 2V to 6V, making it compatible with various power supply configurations.
2. Synchronous Counting:
- The counter operates synchronously with a positive-edge triggered clock input (CP).
- The synchronous nature ensures the outputs change simultaneously and at the same time as the clock.
3. Presettable Counter:
- The SNJ54HC161J features parallel loading capability, allowing users to set the initial value of the counter.
- Parallel loading is accomplished by applying the desired binary number on the preset inputs (P0, P1, P2, P3) and then activating the asynchronous Load (LD) input.
4. 4-Bit Binary Counter:
- The IC acts as a 4-bit binary counter, sequentially counting from 0 to 15 (in decimal) based on clock transitions and control inputs
