It achieves the high speed operation similar to equiva- lent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Pin configuration and function are the same as the VHC04 but the inputs have hysteresis between the positive-going and negative-going input thresholds, which are capable of transforming slowly changing input signals into sharply defined, jitter-free out- put signals, thus providing greater noise margin than con- ventional inverters. An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply volt- age. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This cir- cuit prevents device destruction due to mismatched supply and input voltages. Features s High Speed: tPD = 5.5 ns (typ) at VCC = 5V s Low power dissipation: ICC = 2 µA (Max) at TA = 25°C s High noise immunity: VNIH = VNIL = 28% VCC (Min) s Power down protection is provided on all inputs s Low noise: VOLP = 0.8V (Max) s Pin and function compatible with 74HC14 Ordering Code: Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
