The SN74AC14D from Texas Instruments is a high-speed, Hex Schmitt-trigger Inverter. It is capable of operating from a single power supply over a wide range of voltages, from 1.65 V to 5.5 V. The Schmitt-trigger action provides clean output signals for slow input transition, and the gate's low static power dissipation makes it useful for battery-operated systems. The device is also optimized for applications that use Standard TTL logic families. With its significant features, the SN74AC14D is widely used to buffer, invert, and drive an asynchronous TTL input signal.
