74ALVCH32245屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由意法半導體集團制造生產(chǎn)的74ALVCH32245緩沖器，驅動器，接收器，收發(fā)器邏輯緩沖器、驅動器、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。

DESCRIPTION

The 74ALVCH32245 is a low voltage CMOS 32-BIT BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. It is ideal for 1.65 to 3.6 V applications; it can be interfaced to 3.6V signal enviroment for both inputs and outputs.
