74AC399SCX

The 74AC399SCX is an integrated circuit (IC) component that belongs to the family of 74AC series. It is a 8-bit parallel-in/serial-out shift register with storage capability. Here is an overview of its key features: 1. Shift Register Functionality: The 74AC399SCX facilitates the parallel-to-serial data conversion using an 8-bit input (D0-D7) that can be loaded into the internal shift register. The data will be shifted out through the serial output (Q7) upon subsequent clock pulses. 2. Serial Data Storage: This IC component includes a storage register that enables the storage of the parallel data. By activating the input control pins (S0 and S1), the parallel data can be loaded simultaneously into both the shift register and the storage register. 3. Asynchronous and Synchronous Inputs: The 74AC399SCX provides both asynchronous and synchronous inputs that control the loading and shifting operations. The asynchronous Master Reset (MR) input allows for immediate clearing of all registers when asserted. The synchronous Control (CLK) input controls the shifting and loading control signals based on rising edges. 4. Cascadable Design: Multiple 74AC399SCX ICs can be cascaded to increase the number of bits in the shift register. By connecting the serial output (Q7) of one IC to the serial input (D0) of the next IC, a larger shift register can be formed
