CD74HC4049NS集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

CD74HC4049NS屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的CD74HC4049NS緩沖器，驅(qū)動器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅(qū)動負(fù)載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進(jìn)行隔離通信。

Description

The ’HC4049 and ’HC4050 are fabricated with high-speed

silicon gate technology. They have a modified input

protection structure that enables these parts to be usedas

logic level translators which convert high-level logic to a lowlevel

logic while operating off the low-level logic supply. For

example, 15-V input pulse levels can be down-converted to

0-V to 5-V logic levels. The modified input protection

structure protects the input from negative electrostatic

discharge. These parts also can be used as simple buffers

or inverters without level translation. The ’HC4049 and

’HC4050 are enhanced versions of equivalent CMOS types.
