MM74HC273集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

MM74HC273屬于集成電路（IC）的觸發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的MM74HC273觸發(fā)器觸發(fā)器是能夠存儲單個邏輯狀態(tài)或信息“位”的基本數(shù)字存儲器件。這些器件至少有兩個輸入；一個或多個用于傳遞要存儲的數(shù)據(jù)，另一個用于指示存儲該數(shù)據(jù)的時間點。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對提供給其輸入的信號有不同的響應(yīng)，可用于實現(xiàn)不同的邏輯功能。這些器件與鎖存器的不同之處在于它們是邊緣敏感器件，其保持的邏輯狀態(tài)僅在接收到有效時鐘信號時才會改變。

General Description

The MM74HC273 edge triggered flip-flops utilize advanced silicon-gate CMOS technology to implement D-type flip-flops. They possess high noise immunity, low power, and speeds comparable to low power Schottky TTL circuits. This device contains 8 master-slave flip-flops with a common clock and common clear. Data on the D input having the specified setup and hold times is transferred to the Q output on the LOW-to-HIGH transition of the CLOCK input. The CLEAR input when LOW, sets all outputs to a low state.

Features

■ Typical propagation delay: 18 ns

■ Wide operating voltage range

■ Low input current: 1 μA maximum

■ Low quiescent current: 80 μA (74 Series)

■ Output drive: 10 LS-TTL loads
