74ACT11074N集成电路（IC）的触发器规格书PDF中文资料

74ACT11074N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74ACT11074N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

This device contains two independent positive-edge-triggered D-type flip-flops. A low level at the preset (PRE)

or clear (CLR) input sets or resets the outputs regardless of the levels of the other inputs. When PRE and CLR

are inactive (high), data at the data (D) input meeting the setup-time requirements are transferred to the outputs

on the low-to-high transition of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly

related to the rise time of the clock pulse. Following the hold time interval, data at the D input may be changed

without affecting the levels at the outputs.

The 74ACT11074 is characterized for operation from –40°C to 85°C.
