The 74HC73D,652 is a high-speed CMOS integrated circuit (IC) component that belongs to the 74HC series of logic devices. It is a dual negative-edge triggered JK flip-flop with a preset and a clear function. Here is an overview of its key features:
1. Dual JK Flip-Flop: The 74HC73D,652 consists of two separate JK flip-flops integrated into a single IC. Each flip-flop has independent J, K, preset (PRE), clear (CLR), and clock (CLK) inputs, along with complementary Q and Q outputs.
2. Negative-Edge Triggered: This IC is specifically designed to trigger on the falling edge (negative-edge) of the clock signal (CLK). The flip-flops latch the J and K inputs' current states when this negative-edge occurs.
3. J and K Inputs: The J and K inputs are used to control the state of the flip-flops. Based on the combination of these inputs and the clock signal, the outputs Q and Q change accordingly.
4. Preset (PRE) and Clear (CLR) Inputs: The 74HC73D,652 also includes preset and clear inputs to set or reset the flip-flops to a specific state, regardless of the clock signal. The PRE input sets the outputs to logic HIGH, while the CLR input resets them to logic LOW
