CD4013中文资料Dual D Flip-Flop数据手册TI规格书

描述 Description

General Description
The CD4013B dual D flip-flop is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement mode transistors. Each flip-flop has independent data, set, reset, and clock inputs and ‘‘Q’’ and ‘‘Q’’ outputs. These devices can be used for shift register applications, and by connecting ‘‘Q’’ output to the data input, for counter and toggle applications. The logic level present at the ‘‘D’’ input is transferred to the Q output during the positive-going transition of the clock pulse. Setting or resetting is independent of the clock and is accomplished by a high level on the set or reset line respectively.

简介

CD4013属于集成电路（IC）的触发器。由TI制造生产的CD4013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。
