描述 Description

The 74LCX00 device is a low-voltage CMOS quad dual input NAND gate manufactured with sub-micron silicon gate and double layer metal wiring C2MOS technology. It is ideal for low-power and high-speed 3.3 V applications and can be interfaced to a 5 V signal environment for inputs.
It has the same speed performance at 3.3 V as the 5 V AC/ACT family, combined with lower power consumption.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.

簡(jiǎn)介

74LCX00屬于集成電路（IC）的門反相器。由制造生產(chǎn)的74LCX00門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。
