| 74LVQ14 Low Voltage Hex Inverter with Schmitt Trigger Input May 1998 74LVQ14 Low Voltage Hex Inverter with Schmitt Trigger Input General Description 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. Features 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 75 Ordering Code: Order Number 74LVQ14SC 74LVQ14SJ Package Number M14A M14D Package Description 14-Lead (0.150" Wide) Molded Small Outline Integrated Circuit, SOIC JEDEC 14-Lead Small Outline Package, SOIC EIAJ Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: Unused inputs must be held HIGH or LOW. They may not float.
