M74HCT14TTR集成电路（IC）的门反相器规格书PDF中文资料

M74HCT14TTR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M74HCT14TTR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 M74HCT14 is an high speed CMOS HEX SCHMITT INVERTER fabricated with silicon gate C2MOS technology.

Pin configuration and function are the same as those of the M74HCT04 but all inputs have 0.7 V hysteresis level. This together with its schmitt trigger function allows it to be used on line receiver with slow rise/fall input signals.

■ HIGH SPEED:

tPD = 19ns (TYP.) at VCC = 4.5V

■ LOW POWER DISSIPATION:

ICC = 1µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY :

VH = 0.7V (TYP) at Vcc = 4.5V

■ BALANCED PROPAGATION DELAYS:

tPLH ≅ tPHL

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA (MIN)

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14
