DESCRIPTION

The M74HC14 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 M74HC04 but all inputs have 20 Vcc hysteresis level. This, together with its schmitt trigger function, allows it to be used on line receivers with slow rise/fall input signals.

All inputs are equipped with protection circuits against static discharge and transient excess

voltage.

■ HIGH SPEED: tPD =12ns (TYP.) at VCC = 6V

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

■ HIGH NOISE IMMUNITY: VH = 1.2 V (TYP.) AT VCC = 6 V

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

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

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

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14

M74HC14B1R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M74HC14B1R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。
