74LVQ14 Low Voltage Hex Inverter with Schmitt Trigger Input General Description Features The LVQ14 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 LVQ14 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. n Ideal for low power/low noise 3.3V applications 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 Ordering Code: Order Number Package Number Package Description 74LVQ14SC M14A 14-Lead (0.150" Wide) Molded Small Outline Integrated Circuit, SOIC JEDEC 74LVQ14SJ M14D 14-Lead Small Outline Package, SOIC EIAJ Devices also available in Tape and Reel.
