74LCX14TTR集成電路（IC）的門(mén)反相器規(guī)格書(shū)PDF中文資料

74LCX14TTR屬于集成電路（IC）的門(mén)反相器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的74LCX14TTR門(mén)和反相器邏輯柵極和逆變器系列中的產(chǎn)品對(duì)單個(gè)邏輯信號(hào)執(zhí)行基本邏輯運(yùn)算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲(chǔ)信息，不會(huì)對(duì)提供給其輸入的信號(hào)立即做出響應(yīng)。雖然早就被集成電路實(shí)施形式所取代，以用于實(shí)現(xiàn)復(fù)雜功能，但分立柵極仍可在僅需要非常簡(jiǎn)單邏輯功能的情況下使用。

Description

The 74LCX14 is a low voltage CMOS HEX SCHMITT inverter fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications. It can be interfaced to 5V signal environment for inputs.

Features

■ High speed:

–tPD= 5.0ns (Max) at VCC = 3V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

–|IOH| = IOL= 24mA (Min) at VCC= 3V

■ PCI bus levels guaranteed at 24mA

■ Balanced propagation delays:

–tPLH ?t PHL

■ Operating voltage range:

–VCC(Opr) = 2.0V to 3.6V

■ Pin and function compatible with 74 series 14

■ Latch-up performance exceeds 500mA (JESD 17)

■ ESD performance:

– HBM > 2000V (MIL STD 883 method 3015); MM > 200V
