DESCRIPTION
The 74LVC14A is a low voltage CMOS HEX
SCHMITT INVERTER fabricated with sub-micron
silicon gate and double-layer metal wiring C
technology. It is ideal for 1.65 to 3.6 V

It can be interfaced to 5V signal environment for
inputs in mixed 3.3/5V system.
It has more sp eed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
Pin configuration and function are the same as
those of the 74LVC04A but the 74LVC14A has
hysteresis between the positive and negative
input threshold typically of 700mV.
All inputs and outputs are equipped with
protection circuits against static disc harge, giving
them 2KV ESD immunity and transient excess
voltage.
