74ALVCH16245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74ALVCH16245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(fǎng)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(xiàn)之間進(jìn)行隔離通信。

The 74ALVCH16245 is an advanced performance, non–inverting 16–bit transceiver. It is designed for very high–speed, very low–power operation in 1.8 V, 2.5 V or 3.3 V systems. The 74ALVCH16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16–bit wide function. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bi–directional transceiver.
