74HC377D-Q100集成电路（IC）的触发器规格书PDF中文资料

74HC377D-Q100属于集成电路（IC）的触发器。由安世半导体(中国)有限公司制造生产的74HC377D-Q100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。

1. General description

The 74HC377-Q100; 74HCT377-Q100 is an octal positive-edge triggered D-type flip-flop. The

device features clock (CP) and data enable (E) inputs. When E is LOW, the outputs Qn assume

the state of their corresponding Dn inputs that meet the set-up and hold time requirements on

the LOW-to-HIGH clock (CP) transition. Input E must be stable one set-up time prior to the

LOW-to-HIGH transition for predictable operation. Inputs include clamp diodes that enable the use

of current limiting resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
