The SN74LS93N is a TTL (Transistor-Transistor Logic) integrated circuit that functions as a 4-bit binary counter. It can count in binary from 0000 to 1111 and is commonly used in various digital applications for frequency division, frequency synthesis, and counting. This high-speed 4-bit ripple counter features a divide-by-eight segment that's activated by a transition from HIGH-to-LOW on the clock input. For more details about this counter pinout, circuit diagram, etc can check the SN74LS93N datasheet or 74LS93 guide.

FAQ
How many numbers can a 4-bit binary counter count?
It has the capability to count from 0 to 15, and this counting process is triggered by a digital clock signal that is appropriately connected to the input pin.
How does a 4-bit binary ripple counter work?
This circuit is a 4-bit binary ripple counter. Utilizing JK flip-flops, this counter employs a clever strategy, toggling their state during a downward transition in the clock input. The magic happens as each flip-flop's output feeds into the next one's clock input, creating a seamless flow of counting. When a bit transitions from 1 to 0, it imparts a "carry" effect, adding a delightful touch to the overall counting process.
