74LVQ14
Low Voltage Hex Inverter with Schmitt Trigger Input
General Description
Features
n Ideal for low power/low noise 3.3V applications
The LVQ14 contains six inverter gates each with a Schmitt
trigger input. They are capable of transforming slowly chang-
ing input signals into sharply defined, jitter-free output sig-
nals. In addition, they have a greater noise margin than con-
ventional inverters.
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Guaranteed pin-to-pin skew AC performance
n Guaranteed incident wave switching into 75Ω
The LVQ14 has hysteresis between the positive-going and
negative-going input thresholds (typically 1.0V) which is de-
termined internally by transistor ratios and is essentially in-
sensitive to temperature and supply voltage variations.

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be op-
erated at these limits. The parametric values defined in the Electrical Charac-
teristics tables are not guaranteed at the absolute maximum ratings. The
“Recommended Operating Conditions” table will define the conditions for ac-
tual device operation.
