SN74LVC74ADR集成电路（IC）的触发器规格书PDF中文资料

SN74LVC74ADR属于集成电路（IC）的触发器。由德州仪器制造生产的SN74LVC74ADR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。

3 Description

The SNx4LVC74A devices integrate two positive-edge

triggered D-type flip-flops in one convenient device.

The SN54LVC74A is designed for 2.7V to 3.6V VCC

operation, and the SN74LVC74A is designed for

1.65V to 3.6V VCC operation.
