The 74F676SC is a popular Integrated Circuit (IC) component that belongs to the 74F series of logic devices. It is primarily known as an 8-bit transparent latch, featuring eight individual D-type flip-flops with asynchronous Clear inputs. Here is a comprehensive overview of the 74F676SC, along with its key features:
1. Functional Description: The 74F676SC consists of eight flip-flops with a common Enable (G) input and eight complementary outputs (Q and Q?). The D inputs control the Q outputs according to the clock (CP) transitions. When the Enable (G) is low, the latch is transparent, allowing the D inputs to pass through to the Q outputs when a clock pulse occurs.
2. Clock (CP) Input: The 74F676SC has an active-low Clock (CP) input, which triggers the flip-flops to capture the data at the D inputs and transfers it to the Q outputs on the rising edge of the clock signal. The clock input controls the data transfer within the IC.
3. Asynchronous Clear (CLR) Input: This IC includes an asynchronous Clear (CLR) input, which when activated (low logic level), sets all the Q outputs to low state (logic "0"). This feature allows a quick reset of all flip-flops to a known initial state independently of the clock
