74V1G14集成电路（IC）的门反相器规格书PDF中文资料

74V1G14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74V1G14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 74V1G14 is an advanced high-speed CMOS SINGLE SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output.

Power down protection is provided on input and 0 to 7V can be accepted on input with no regard to the supply voltage. This device can be used to interface 5V to 3V. Pin configuration and function are the same as those of the 74V1G04 but the 74V1G14 has hysteresis.

This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals.

The input is equipped with protection circuits against static discharge, giving it ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 4.3ns (TYP.) at VCC = 5V

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

■ TYPICAL HYSTERESIS: Vh=1V at VCC=4.5V

■ POWER DOWN PROTECTION ON INPUT

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8mA (MIN) at VCC = 4.5V

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY
