74LVC374中文资料74LVC374: Low Voltage CMOS Octal D Flip-Flop数据手册ONSEMI规格书

描述 Description

The 74LVC374A is a high performance, non-inverting octal D-type flip-flop operating from a 1.2 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows 74LVC374A inputs to be safely driven from 5V devices.The 74LVC374A consists of 8 edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The buffered clock and buffered Output Enable (OEbar) are common to all flip-flops. The eight flip-flops will store the state of individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition. Withthe OEbar LOW, the contents of the eight flip-flops are available at the outputs. When the OEbar is HIGH, the outputs go to the high impedance state. The OEbar input level does not affect the operation of the flip-flops.

简介

74LVC374属于集成电路（IC）的触发器。由ONSEMI制造生产的74LVC374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。
