MC74LVX4245集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

MC74LVX4245屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74LVX4245緩沖器，驅(qū)動器，接收器，收發(fā)器邏輯緩沖器、驅(qū)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(qū)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。

Dual Supply Octal Translating Transceiver

with 3?State Outputs

The 74LVX4245 is a 24?pin dual?supply, octal translating transceiver that is designed to interface between a 5.0 V bus and a 3.0 V bus in a mixed 3.0 V / 5.0 V supply environment such as laptop computers using a 3.3 V CPU and 5.0 V LCD display. The A port interfaces with the 5V bus; the B port interfaces with the 3.0 V bus.

The Transmit/Receive (T/R) input determines the direction of data flow. Transmit (active?High) enables data from the A port to the B port. Receive (active?Low) enables data from the B port to the A port. The Output Enable (OE) input, when High, disables both A and B ports by placing them in 3?State.
