MC74LCX540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

MC74LCX540屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由安森美半導體公司制造生產(chǎn)的MC74LCX540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)總線之間進行隔離通信。

The MC74LCX540 is a high performance, inverting octal buffer

operating from a 2.3 to 3.6 V supply. This device is similar in function

to the MC74LCX240, while providing flow through architecture.

High impedance TTL compatible inputs significantly reduce current

loading to input drivers while TTL compatible outputs offer improved

switching noise performance. A VI specification of 5.5 V allows

MC74LCX540 inputs to be safely driven from 5 V devices. The

MC74LCX540 is suitable for memory address driving and all TTL

level bus oriented transceiver applications.

Current drive capability is 24 mA at the outputs. The Output Enable

(OE1, OE2) inputs, when HIGH, disables the outputs by placing them

in a HIGH Z condition.
