74AC02M集成电路（IC）的门反相器规格书PDF中文资料

74AC02M属于集成电路（IC）的门反相器。由意法半导体集团制造生产的74AC02M门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。

DESCRIPTION

The 74AC02 is an advanced high-speed CMOS QUAD 2-INPUT NOR GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

The internal circuit is composed of 3 stages including buffer output, which enables high noise immunity and stable output. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage

■ HIGH SPEED: tPD = 4.2ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION: ICC = 2µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)

■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 02

■ IMPROVED LATCH-UP IMMUNITY
