DESCRIPTION

The 74LVC14A is a low voltage CMOS HEX
SCHMITT INVERTER fabricated with sub-micron
silicon gate and double -layer metal wiring C

technology. I t is ideal for 1.65 to 3.6 V

CC

operations and low power and low noise
applications.

It can be interfaced to 5V signal environm ent f or
inputs in mixed 3.3/5V system.
It has more speed performance a t 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 e quipped with
protection circuits aga inst static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
