MC74LVX74中文资料Dual D Flip-Flop数据手册ONSEMI规格书

描述 Description

The MC74LVX74 is an advanced high speed CMOS D-type flip-flop. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems. The signal level applied to the D input is transferred to O output during the positive going transition of the Clock pulse. Clear (CD) and Set (SD) are independent of the Clock (CP) and are accomplished by setting the appropriate input Low.

特性 Features

• High Speed: fmax = 145MHz (Typ) at VCC = 3.3V
• Low Power Dissipation: ICC = 2µA (Max) at TA = 25 C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: VOLP = 0.5V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V PIN
• Pb-Free Packages are Available

简介

MC74LVX74属于集成电路（IC）的触发器。由制造生产的MC74LVX74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。
