74VHC14MTC

Features General Description • • • • • • The VHC14 is an advanced high speed CMOS Hex Schmitt Inverter fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent 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, jitterfree output signals, thus providing greater noise margin than conventional inverters. An input protection circuit ensures that 0 V to 7 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. High Speed: tPD = 5.5 ns (Typ.) at VCC = 5 V Low Power Dissipation: ICC = 2 μA (Max.) at TA = 25°C High Noise Immunity: VNIH = VNIL = 28% VCC (Min.) Power down protection is provided on all inputs Low Noise: VOLP = 0.8 V (Max.)

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.

Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. The data book specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. ON Semiconductor does not recommend operation outside data-book specifications. www.onsemi.com 2 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.
