MC74LCX74D集成电路（IC）的触发器规格书PDF中文资料

MC74LCX74D属于集成电路（IC）的触发器。由安森美半导体公司制造生产的MC74LCX74D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。

Low−Voltage CMOS Dual D−Type Flip−Flop With 5 V−Tolerant Inputs

The MC74LCX74 is a high performance, dual D−type flip−flop with asynchronous clear and set inputs and complementary (O, O) outputs. It operates from a 2.3 to 3.6 V 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 5.5 V allows MC74LCX74 inputs to be safely driven from 5.0 V devices.
