DESCRIPTION
The 74LVQ14 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 and low noise
3.3V applications.
The internal circuit is composed of 3 stages

including buffer output, which enables high noise
immunity and stable output.
Pin configuration and function are the same as
those of the 74LVQ04 but the 74LVQ14 has
hysteresis between the positive and negative
input threshold typically of 650mV.
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.

1) CPD 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. ICC(opr) = CPD x VCC x fIN + ICC/6 (per gate)

CL = 50pF or equivalent (includes jig and probe capacitance)
RL = 500Ω or equivalent
RT = ZOUT of pulse generator (typically 50Ω)
