DESCRIPTION
The 74LVX14 is a low voltage CMOS HEX
SCHMITT INVERTER fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage.
This device can be used to interface 5V to 3V
system. It combines high speed pe rformance with
the true CMOS low power consum ption.
Pin configuration and function are the same as
those of the 74LVX00 but the 74LVX14 has
hysteresis between the positive and the negative
input threshold typi call y of 1V.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fall input signals.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

Table 8: AC Electrical Characteristics (Input tr = tf = 3ns)
1) Skew is def ined as the absolut e value of the dif ference between the actual propagation delay for any two outputs of the s ame device switch-
in g i n the same di rectio n, either HIG H or LOW
2) Parameter guarante ed by design
(*) Voltage range is 3.3V ± 0.3V
Table 9: Capacitive Characteristics
1) C PD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I CC(opr) = CPD x V CC x fIN + ICC/6 (per gate)
