SY100EL31中文资料Flip Flops, Registers Products数据手册Microchip规格书

描述 Description

The SY10/100EL31 are D flip-flops with set and reset. The devices are functionally equivalent to the E131 devices, with higher performance capabilities. With propagation delays and output transition times significantly faster than the E131, the EL31 is ideally suited for those applications which require the ultimate in AC performance.Both the set and reset inputs are asynchronous, level triggered signals. Data enters the master portion of the flip-flop when the clock is LOW and is transferred to the slave, and thus the outputs, upon a positive transition of the clock.

特性 Features

·475ps propagation delay
·2.8GHz toggle frequency
·Internal 75KΩ input pull-down resistors
·Available in 8-pin SOIC package

简介

SY100EL31属于集成电路（IC）的触发器。由制造生产的SY100EL31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。
