74HC245集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

74HC245屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的74HC245緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動(dòng)器、接收器和收發(fā)器允許隔離對(duì)某個(gè)電路的邏輯信號(hào)的訪問(wèn)，以用于另一電路。緩沖器將其輸入信號(hào)（不變或反相）傳遞到其輸出，并可能用于清除弱信號(hào)或驅(qū)動(dòng)負(fù)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(jìn)行隔離通信。

Octal 3?State Noninverting Bus Transceiver

High?Performance Silicon?Gate CMOS

The 74HC245 is identical in pinout to the LS245. The device inputs are compatible with standard CMOS outputs; with pull?up resistors, they are compatible with LSTTL outputs.

The HC245 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.
