MC74LVX374集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

MC74LVX374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MC74LVX374觸發(fā)器觸發(fā)器是能夠存儲(chǔ)單個(gè)邏輯狀態(tài)或信息“位”的基本數(shù)字存儲(chǔ)器件。這些器件至少有兩個(gè)輸入；一個(gè)或多個(gè)用于傳遞要存儲(chǔ)的數(shù)據(jù)，另一個(gè)用于指示存儲(chǔ)該數(shù)據(jù)的時(shí)間點(diǎn)。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對(duì)提供給其輸入的信號(hào)有不同的響應(yīng)，可用于實(shí)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(shí)鐘信號(hào)時(shí)才會(huì)改變。

Octal D-Type Flip-Flop with 3-State Outputs

With 5V?Tolerant Inputs

The MC74LVX374 is an advanced high speed CMOS octal D?type flip?flop with 3?state outputs. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.

This 8?bit D?type flip?flop is controlled by a clock input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.
