DESCRIPTION

The M54/74HC266/7266 are high speed CMOS QUAD EXCLUSIVE NOR GATES, fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption.

■ HIGH SPEED tPD = 10 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 1 µA (MAX.) AT TA = 25 °C

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

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE (7266) |IOH| = IOL = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS (7266) tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS7266

M74HC266属于集成电路（IC） > 门和反相器。意法半导体（ST）集团制造生产的M74HC266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。
