The IC component N74F191D,623 is a 4-bit synchronous binary up/down counter. It is manufactured by Nexperia, a leading semiconductor company.
Key features of the N74F191D,623 include:
1. Binary Up/Down Counter: This IC can count up or down depending on the state of the control inputs. It has separate up and down count inputs, making it suitable for numerous counting applications.
2. Synchronous Operation: The counter operates synchronously with the clock input, ensuring reliable and glitch-free counting. The outputs change simultaneously with the rising edge of the clock signal.
3. Asynchronous Parallel Load: It has a parallel load feature that enables the user to preset the initial value of the counter by loading data into it asynchronously using the parallel data inputs.
4. Cascadable: This IC is designed to be cascaded, meaning multiple counters can be connected together to create wider counting capabilities. The carry output of one counter can be connected to the carry input of the next counter for seamless expansion.
5. Reset Functionality: The N74F191D,623 includes a reset input that sets all outputs to zero when activated. This allows for easy initialization of the counter.
6. Low Power Consumption: The IC is designed to operate at low power, making it suitable for battery-powered applications where energy efficiency is crucial.
Overall, the N74F191D,623 is a versatile and reliable synchronous up/down counter IC with parallel load capability
