SN74LV1T08集成電路（IC）的門反相器規(guī)格書PDF中文資料

SN74LV1T08屬于集成電路（IC）的門反相器。由德州儀器制造生產(chǎn)的SN74LV1T08門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對(duì)單個(gè)邏輯信號(hào)執(zhí)行基本邏輯運(yùn)算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲(chǔ)信息，不會(huì)對(duì)提供給其輸入的信號(hào)立即做出響應(yīng)。雖然早就被集成電路實(shí)施形式所取代，以用于實(shí)現(xiàn)復(fù)雜功能，但分立柵極仍可在僅需要非常簡(jiǎn)單邏輯功能的情況下使用。

3 Description

The SN74LV4T125-EP contains four independent

buffers with 3-state outputs and extended voltage

operation to allow for level translation. Each buffer

performs the Boolean function Y = A in positive logic.

The outputs can be put into a high impedance (Hi-Z)

state by applying a HIGH on the OE pin. The output

level is referenced to the supply voltage (VCC) and

supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.

The input is designed with a lower threshold circuit to

support up translation for lower voltage CMOS inputs

(for example, 1.2V input to 1.8V output or 1.8V input

to 3.3V output). In addition, the 5V tolerant input pins

enable down translation (for example, 3.3V to 2.5V

output).
