SN74HC273QDWRG4Q1集成电路（IC）的触发器规格书PDF中文资料

SN74HC273QDWRG4Q1属于集成电路（IC）的触发器。由美国德州仪器公司制造生产的SN74HC273QDWRG4Q1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。

description/ordering information

This circuit is a positive-edge-triggered D-type

flip-flop with a direct clear (CLR) input.

Information at the data (D) inputs meeting the setup

time requirements is transferred to the Q outputs on

the positive-going edge of the clock (CLK) pulse.

Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the

positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
