74ACT16245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

74ACT16245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74ACT16245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，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。

DESCRIPTION

The 74ACT16245 is an advanced high-speed CMOS 16-BIT BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by DIR input. The enable inputs G can be used to disable the device so that the buses are effectively isolated.

All floating bus terminals during the Z-state must be held HIGH or LOW.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 4.9ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 8μA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS

VIH = 2V (MIN.), VIL = 0.8V (MAX.)

■ 50? TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 24mA (MIN)

■ OPERATING VOLTAGE RANGE:

VCC (OPR) = 4.5V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY
