The SN74ABT821ADBR is an Integrated Circuit (IC) component that belongs to the SN74ABT821A family of counters and registers. It is designed to function as an 8-bit D-type flip-flop with a parallel to serial data conversion capability, making it suitable for various digital applications. Here is an overview of its key features:
1. Functionality: The IC operates as an 8-bit D-type flip-flop, capable of storing and controlling binary information. It can latch data on the positive edge of the clock signal and provide synchronous parallel outputs. Additionally, it can perform parallel to serial data conversion when a special output control line is activated.
2. Input/Output Configuration: The SN74ABT821ADBR supports 8-bit parallel input and output, allowing for efficient data manipulation. The parallel inputs control the stored state of the flip-flop, while the parallel outputs reflect this stored information.
3. Clock Control: An external clock signal synchronizes the data transfer within the flip-flop. When the clock input receives a positive transition, the IC stores the data present at the D inputs. This synchronous operation ensures accurate and stable data transfer.
4. Serial Data Output: The IC features a dedicated output pin for serial data transmission. When the output control line is enabled, the stored parallel data is shifted out in a serial fashion on this pin. This capability is useful in applications where serial data transmission is required
