74ACTQ821数据手册集成电路（IC）的触发器规格书PDF

描述 Description

General Description
The ACTQ821 is a 10-bit D-type flip-flop with non-inverting 3-STATE outputs arranged in a broadside pinout. The ACTQ821 utilizes Fairchild’s Quiet Series™ technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.

特性 Features

■ Guaranteed simultaneous switching noise level and dynamic threshold performance
■ Guaranteed pin-to-pin skew AC performance
■ Non-inverting 3-STATE outputs for bus interfacing
■ 4 kV minimum ESD immunity
■ Outputs source/sink 24 mA

简介

74ACTQ821属于集成电路（IC）的触发器。由制造生产的74ACTQ821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。
