ESD PERFORMANCE: It has more speed performance at 3.3V than 5V HBM > 2000V (MIL STD 883 method 3015) AC/ACT family, combined with a lower power MM > 200V consumption. Pin configuration and function are the same as DESCRIPTION those of the 74LVC04A but the 74LVC14A has hysteresis between the positive and negative The 74LVC14A is a low voltage CMOS HEX SCHMITT INVERTER fabricated with sub-micron input threshold typically of 700mV. 2 All inputs and outputs are equipped with silicon gate and double-layer metal wiring C MOS protection circuits against static discharge, giving technology. It is ideal for 1.65 to 3.6 V CC them 2KV ESD immunity and transient excess operations and low power and low noise applications. voltage.
