概述

Description

The SN74HC574DWR is a high-speed, octal flip-flop designed for use in digital circuits. It features eight D-type flip-flops with output enable controls, allowing for synchronous data storage. This device operates with a wide voltage range (2V to 6V) and is compatible with TTL (Transistor-Transistor Logic) levels, making it suitable for various logic applications.
The SN74HC574DWR has two data inputs for each flip-flop, a clock input, and an output enable input. Data is latched on the rising edge of the clock, allowing for reliable data retention and transfer. With a maximum propagation delay of around 15 ns at 5V, it supports high-speed operation, making it ideal for applications requiring fast data processing.
It is available in a 20-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is suitable for compact electronic designs. The SN74HC574DWR is commonly used in shift registers, memory buffers, and other digital logic applications where data storage and transfer are essential.

Features

The SN74HC574DWR is a high-speed, low-power octal D-type flip-flop with 3-state outputs. Key features include:
1. 8-bit Storage: It allows for the storage of 8 bits of data.
2. D-Type Logic: Each flip-flop has a data input (D), a clock input (CLK), and an active-low output enable (OE).
3. Edge-Triggered: The flip-flops are triggered on the rising edge of the clock signal, ensuring synchronized data storage.
4. 3-State Outputs: Outputs can be placed in high-impedance state, allowing for bus interfacing.
5. Wide Operating Voltage Range: Operates between 2V to 6V, making it versatile for various applications.
6. High Speed: Typical propagation delays are low, facilitating fast data processing.
7. Low Power Consumption: Designed for low power operation, suitable for battery-powered devices.
8. TTL Compatible: The device is compatible with TTL logic levels, making integration with existing circuits straightforward.
The SN74HC574DWR is ideal for data storage, temporary buffering, and interfacing applications in digital systems.

Package

The SN74HC574DWR is a 20-pin Dual In-line Package (DIP) with a wide body. Specifically, it is a surface-mount package known as TSSOP (Thin Shrink Small Outline Package). The 'DWR' suffix indicates the package type along with the temperature range and other specifications.

Pinout

The SN74HC574DWR is an octal D flip-flop with a tri-state output, and it features a total of 20 pins. Its main function is to store and transfer data in digital circuits. The device has eight data inputs (D0 to D7), eight outputs (Q0 to Q7), and additional control pins including:
- GND: Ground connection.
- VCC: Power supply connection (typically +2V to +6V).
- OE (Output Enable): Active low control for enabling/disabling the outputs.
- CLK: Clock input which triggers the storage of data from the inputs to the outputs on the rising edge.
- MR (Master Reset): Active low input that resets all outputs to low when asserted.
The SN74HC574 is commonly used in applications requiring temporary data storage, such as shift registers, memory buffers, and data latches in digital systems.
