概述

Description

The SN74HC574PWR is an octal (8-bit) D-type flip-flop designed for high-speed operation in digital circuits. It features a transparent latch that captures input data on the rising edge of the clock signal, allowing for the storage and retrieval of binary information. The "HC" in its name indicates that it operates at high speed with low power consumption, compatible with standard TTL logic levels.
The device has two sets of eight D inputs and outputs, with an asynchronous reset feature that can clear all outputs to a low state. It operates with a supply voltage of 2V to 6V and is suitable for various applications, including data storage, register files, and temporary data holding in digital systems.
The SN74HC574PWR is available in a TSSOP (Thin Shrink Small Outline Package) form factor, making it suitable for space-constrained designs. Its reliability and versatility make it a popular choice in both consumer electronics and industrial applications.

Features

The SN74HC574PWR is an octal D-type flip-flop with 3-state outputs, designed for high-speed data processing. Key features include:
1. Functionality: It captures data on the rising edge of the clock, providing synchronized output.
2. Data Inputs: It has eight D inputs for parallel data input.
3. 3-State Outputs: The outputs can be set to high, low, or high impedance, allowing for bus-oriented architecture.
4. Wide Supply Voltage Range: Operates from 2V to 6V, making it compatible with various logic levels.
5. High-Speed Operation: Typical propagation delay is around 15 ns at 5V, enabling high-speed applications.
6. Low Power Consumption: Designed for low power use, making it suitable for battery-operated devices.
7. TTL Compatibility: Compatible with standard TTL logic levels.
8. Package Type: Available in a TSSOP-20 package for space-saving in circuit designs.
These features make the SN74HC574PWR suitable for a wide range of digital applications in communications, computing, and consumer electronics.
