SN74LS652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

SN74LS652屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由德州儀器制造生產(chǎn)的SN74LS652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(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。

description

These devices consist of bus transceiver circuits, D-type

flip-flops, and control circuitry arranged for multiplexed

transmission of data directly from the data bus or from

the internal storage registers. Enable GAB and GBA are

provided to control the transceiver functions. SAB and

SBA control pins are provided to select whether realtime

or stored data is transferred. A low input level selects

real-time data, and a high selects stored data. The

following examples demonstrate the four fundamental

bus-management functions that can be performed with

the 'LS651, 'LS652, and 'LS653.
