74LVX245MTR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

74LVX245MTR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74LVX245MTR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。

DESCRIPTION

The 74LVX245 is a low voltage CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications.

■ HIGH SPEED:

tPD=4.7ns (TYP.) at VCC = 3.3V

■ 5V TOLERANT INPUTS

■ POWER-DOWN PROTECTION ON INPUTS

■ INPUT VOLTAGE LEVEL:

VIL = 0.8V, VIH = 2V at VCC =3V

■ LOW POWER DISSIPATION:

ICC = 4 μA (MAX.) at TA=25°C

■ LOW NOISE:

VOLP = 0.5V (TYP.) at VCC =3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4 mA (MIN) at VCC =3V

■ BALANCED PROPAGATION DELAYS: tPLH ? tPHL

■ OPERATING VOLTAGE RANGE:

VCC(OPR) = 2V to 3.6V (1.2V Data Retention)

■ PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 245

■ IMPROVED LATCH-UP IMMUNITY
