SN74F377ADWR集成电路（IC）的触发器规格书PDF中文资料

SN74F377ADWR属于集成电路（IC）的触发器。由德州仪器制造生产的SN74F377ADWR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

The SN74F377A is a monolithic, positive-edge-triggered, octal, D-type flip-flop with clock enable inputs. The

SN74F377A features a latched clock enable (CE) 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 pulse if CE is low. Clock triggering occurs at a particular voltage level and is

not directly related to the positive-going pulse. When the clock input is at either the high or low level, the D input

signal has no effect at the output. The circuits are designed to prevent false clocking by transitions at the CE

input.

The SN74F377A is characterized for operation from 0°C to 70°C.
