It combines high speed performance with IMPROVED LATCH-UP IMMUNITY the true CMOS low power consumption. POWER DOWN PROTECTION ON INPUTS Pin configuration and function are the same as those of the 74LVX00 but the 74LVX14 has DESCRIPTION hysteresis between the positive and the negative The 74LVX14 is a low voltage CMOS HEX input threshold typically of 1V. SCHMITT INVERTER fabricated with sub-micron This together with its schmitt trigger function 2 silicon gate and double-layer metal wiring C MOS allows it to be used on line receivers with slow technology. It is ideal for low power, battery rise/fall input signals. operated and low noise 3.3V applications. All inputs and outputs are equipped with Power down protection is provided on all inputs protection circuits against static discharge, giving and 0 to 7V can be accepted on inputs with no them 2KV ESD immunity and transient excess regard to the supply voltage. voltage.
