Toshiba Semiconductor and Storage 74HC574D Environmental and export classification status description

The Toshiba 74HC574D is a high-speed CMOS octal D flip-flop. It consists of eight D-type flip-flops with individual data inputs (D), a common clock input (CLK), and individual outputs (Q). The flip-flops store the state of the input data when the clock input transitions from low to high (rising edge). This IC is suitable for various applications requiring digital data storage, signal processing, and timing functions. Functions: - Data Storage: Each flip-flop can hold one bit of data. - Clock Synchronization: The flip-flops are clocked by a single common clock signal. - Edge Triggered: Data is latched on the rising edge of the clock signal. - Output: Each flip-flop has a corresponding output (Q) and an inverted output (Q'). - Enable Input: The flip-flops can be enabled or disabled, allowing for controlled operation. Applications: - Data Buffering: For buffering data and synchronizing signals in digital circuits. - State Storage: Used in digital systems to hold the state information. - Shift Registers: Can be implemented as part of larger shift register circuits. - Timing Circuits: Great for timing and control applications in sequential logic circuits. - Microcontroller Interfaces: Used to interface with microcontrollers for handling multiple data lines. Alternative Parts: Some alternative parts to the Toshiba 74HC574D include: - 74HC374: Similar octal D-type latch with tri-state outputs for bus applications. - 74HC74: Dual D-type flip-flop with independent set and reset inputs. - 74LS574: Low-power Schottky version of the octal flip-flop with similar functionality. Embedded Modules: - FPGA/ASIC implementations: Design engineers may implement similar D flip-flop functionality using FPGAs or custom ASICs. - Microcontroller Libraries: Libraries in microcontroller programming may include simulation of D flip-flop behavior for digital design. - Breadboard modules: Standalone D flip-flop modules available for educational purposes and experimentation in digital electronics.
