MC74LVX574中文资料Octal D Flip-Flop with 3-State Outputs数据手册ONSEMI规格书

描述 Description

The MC74LVX574 is an advanced high speed CMOS octal flip-flopwith 3-state outputs. The inputs tolerate voltages up to 7V, allowing theinterface of 5V systems to 3V systems. This 8-bit D-type flip-flop is controlled by a clock pulse input and anoutput enable input. When the output enable input is high, the eightoutputs are in a high impedance state.

特性 Features

• Low Power Dissipation: ICC = 4mA (Max) at TA = 25°C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: VOLP = 0.8V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V
• Pb-Free Packages are Available*

简介

MC74LVX574属于集成电路（IC）的触发器。由ONSEMI制造生产的MC74LVX574触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。
