DESCRIPTION

The 74V1T14 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 74V1T04 but the 74V1T14 has hysteresis.

■ HIGH SPEED: tPD = 5.0ns (TYP.) at VCC = 5V

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

■ TYPICAL HYSTERESIS: Vh=700mV 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) = 4.5V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY

74V1T14C屬于集成電路（IC） > 門和反相器。意法半導體（ST）集團制造生產(chǎn)的74V1T14C門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對單個邏輯信號執(zhí)行基本邏輯運算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲信息，不會對提供給其輸入的信號立即做出響應。雖然早就被集成電路實施形式所取代，以用于實現(xiàn)復雜功能，但分立柵極仍可在僅需要非常簡單邏輯功能的情況下使用。
