DESCRIPTION
The LVQ14 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

(Micro Package)
T
(TSSOP Package)
ORDER CODES :

including buffer output, which enables high noise
immunity and stable output.
It has better speed performance at 3.3V than 5V
lsttl family combined with the true CMOS low
power consumption.
Pin configuration and function are the same as
those of the LVQ04 but the LVQ14 has hysteresis
between the positive and negative input threshold
typically 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.
