74LCX16245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的74LCX16245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。

DESCRIPTION

The 74LCX16245 is a low voltage CMOS 16 BITBUS TRANSCEIVER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power

and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs

and outputs.

This IC is intended for two-way asynchronous communication between data buses; the direction

of data transmission is determined by DIR input. The two enable inputs nG can be used to disable

the device so that the buses are effectively isolated.
