74VHC14M

The 74VHC14M is an advanced high-speed CMOS Hex Schmitt Inverter from ON Semiconductor, fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low power dissipation. The inputs have hysteresis, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals, thus providing greater noise margin than conventional inverters.

Key electrical specifications include a typical propagation delay of 5.5 ns at 5V, a low power dissipation with a maximum ICC of 2 μA at 25°C, and high noise immunity with input thresholds at 28% of VCC. The device operates over a voltage range of 2V to 5.5V and can source/sink up to 8mA of current. An input protection circuit allows 0V to 5.5V to be applied to the input pins without regard to the supply voltage, preventing device destruction due to mismatched supply and input voltages.

This inverter is suitable for interfacing 5V to 3V systems and two-supply systems. It is pin and function compatible with the 74HC14. The component is supplied in a 14-SOIC surface mount package, designed for efficient integration into electronic circuits.
