SN74HC652NT屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的SN74HC652NT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。

description/ordering information

The ’HC652 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. Output-enable

(OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs

are provided to select real-time or stored-data transfer. A low input level selects real-time data, and a high input

level selects stored data. Figure 1 illustrates the four fundamental bus-management functions that can be

performed with these devices.
