The 74LCX14 is a low voltage hex inverter with 5V tolerant Schmitt trigger inputs, which 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 document describes the Fairchild Semiconductor 74LCX14, which contains six inverter gates each featuring a Schmitt trigger input. This design allows for transforming slowly changing signals into sharply defined outputs while providing greater noise margin than conventional inverters.
Key features include inputs that tolerate voltages up to 7V, enabling the interface of 5V, 3V, and 2.5V systems. The device operates with a supply voltage range of 2.0V to 3.6V for normal operation and is available in various packages including SOIC, SOP, TSSOP, and DQFN.
