MC74HCT245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

MC74HCT245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MC74HCT245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。

Octal 3-State Noninverting Bus Transceiver with LSTTL Compatible Inputs

High?Performance Silicon?Gate CMOS

The MC74HCT245A is identical in pinout to the LS245. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The MC74HCT245A is a 3?state noninverting transceiver that is used for 2?way asynchronous communication between data buses. The device has an active?low Output Enable pin, which is used to place the I/O ports into high?impedance states. The Direction control determines whether data flows from A to B or from B to A.
