HCF4502B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(shū)PDF中文資料

HCF4502B屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的HCF4502B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(xiàn)之間進(jìn)行隔離通信。

DESCRIPTION

The HCC4502B (extended temperature range) and HCF4502B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF 4502B consists of six inverter-buffers with 3-state outputs. A logic ”1” on the OUTPUT DISABLE input produces a highimpedance state in all six outputs. This feature permits common busing of the outputs, thus simplifying system design. A logic”1” on the INHIBIT input switches all six outputs to logic ”0” if the OUTPUT DISABLE input is a logic ”0”. This device is capable of driving two standard TTL loads, which is equivalent to six times the JEDEC ”B” series IOL standard.
