74LVC244A屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的74LVC244A緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動(dòng)器、接收器和收發(fā)器允許隔離對(duì)某個(gè)電路的邏輯信號(hào)的訪問(wèn)，以用于另一電路。緩沖器將其輸入信號(hào)（不變或反相）傳遞到其輸出，并可能用于清除弱信號(hào)或驅(qū)動(dòng)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。

Low-Voltage CMOS Octal Buffer

With 5 V?Tolerant Inputs and Outputs (3?State, Non?Inverting)

The 74LVC244A is a high performance, non?inverting octal buffer operating from a 1.2 to 3.6 V supply. 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 74LVC244A inputs to be safely driven from 5 V devices. The 74LVC244A is suitable for memory address driving and all TTL level bus oriented transceiver applications.
