MC74VHCT244A集成電路（IC）的緩沖器驅動器接收器收發(fā)器規(guī)格書PDF中文資料

MC74VHCT244A屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由安森美半導體公司制造生產的MC74VHCT244A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)器允許在數據總線之間進行隔離通信。

The MC74VHCT244A is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
