Toshiba Semiconductor and Storage 74HC74D Environmental and export classification status description

of Toshiba 74HC74D The Toshiba 74HC74D is a dual D-type flip-flop IC that operates in high-speed CMOS technology. It is part of the 74HC series, which stands for High-Speed CMOS. This particular IC is designed for use in digital logic circuits and is capable of accomplishing various tasks in synchronous digital circuits. Functions - Dual D Flip-Flops: The 74HC74D contains two independent D-type flip-flops with individual data inputs, clock inputs, and outputs. - Edge Triggered: The flip-flops respond to clock inputs on the rising edge, capturing the data present on the D inputs. - Asynchronous Clear and Set: Each flip-flop includes asynchronous clear (CLR) and set (PRE) inputs, allowing for setting or resetting the state independently of the clock. Applications - Data Storage: Used for storing data bits in digital circuits. - State Machines: Useful in creating finite state machines for control applications. - Frequency Division: Can be used in frequency division applications, such as frequency counters and dividers. - Shift Registers: Can be used to build shift registers and delay lines for signal processing. - Synchronization: In digital circuits, for synchronizing signals across different parts of a system. Alternative Parts - 74HC74: The standard dual D flip-flop from other manufacturers like Texas Instruments. - 74HCT74: Similar functionality but with compatibility for TTL levels. - 74LS74: A low-power Schottky version which might be a suitable alternative depending on power consumption requirements. Embedded Modules - FPGA/PLD Implementations: Flip-flops like the 74HC74 can be mimicked in Field Programmable Gate Arrays (FPGAs) and Programmable Logic Devices (PLDs). - Microcontroller GPIO: Many microcontrollers have built-in flip-flop capabilities that can replicate the function of the 74HC74.
