74VHC14MTC Product Information
General Description
The 74VHC14MTC is a high-speed CMOS Hex Schmitt Inverter manufactured using silicon gate CMOS technology. It provides high-speed performance comparable to equivalent Bipolar Schottky TTL while maintaining low power consumption. The device has hysteresis between positive-going and negative-going input thresholds, which helps transform slowly changing input signals into sharply defined, jitter-free output signals, offering greater noise margin than conventional inverters.

Features
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 on All Inputs
Low Noise: VOLP = 0.8 V (Max.)
Pin and Function Compatible with 74HC14
