General Description

The LCX14 contains six inverter gates each with a

Schmitt trigger input. They are capable of transforming

slowly changing input signals into sharply defined, jitter-

free output signals. In addition, they have a greater noise

margin than conventional inverters.

The LCX14 has hysteresis between the positive-going

and negative-going input thresholds (typically 1.0V)

which is determined internally by transistor ratios and is

essentially insensitive to temperature and supply voltage

variations.

The inputs tolerate voltages up to 7V allowing the inter-

face of 5V, 3V and 2.5V systems.

The 74LCX14 is fabricated with advanced CMOS tech-

nology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.

Note:

Absolute Maximum Rating must be observed.

Recommended Operating Conditions

(3)

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to absolute maximum ratings.

Note:

3. Unused inputs must be held HIGH or LOW. They may not float.
