概述

Description

The SN74HC74D is a dual D-type flip-flop integrated circuit from Texas Instruments, part of the 74HC (High-speed CMOS) family. It is designed for use in digital circuits, providing a reliable method for data storage and transfer. Each flip-flop has a data (D) input, a clock (CLK) input, a reset (CLR) input, and output (Q and Q').
When the clock input transitions from low to high, the flip-flop captures the value present at the D input, transferring it to the Q output. The CLR input allows for asynchronous resetting of the flip-flops, setting the Q output to low regardless of the clock state. The SN74HC74D operates on a supply voltage range of 2V to 6V and boasts high-speed performance, making it suitable for various applications, including data storage, registers, and state machines in digital systems. Its dual configuration allows for efficient circuit design, reducing the number of required components.

Features

The SN74HC74D is a dual D-type flip-flop designed for high-speed digital logic applications. Key features include:
1. Dual Functionality: Contains two independent D flip-flops, each with a data input (D), a clock input (CLK), a clear input (CLR), and a preset input (PRE).
2. High-Speed Performance: Operates at high speeds with propagation delays typically around 25 ns at 5V.
3. Wide Power Supply Range: Supports a supply voltage range of 2V to 6V, making it versatile for various applications.
4. Low Power Consumption: Designed for low power operation, making it suitable for battery-powered devices.
5. TTL Compatibility: Compatible with TTL logic levels, enabling easy integration into existing systems.
6. Asynchronous Control Inputs: Allows for clear and preset operations independent of the clock signal.
7. Standard Pin Configuration: Available in a 14-pin DIP or SOIC package, facilitating ease of use in circuit design.
These features make the SN74HC74D ideal for shift registers, data storage, and synchronization in digital circuits.

Package

The SN74HC74D is typically packaged in a dual in-line package (DIP) or a surface-mount package (SOIC). The "D" suffix indicates a small outline IC package, specifically the SOIC form factor.
