The SN74LV14ADR with Inverters Hex Schmitt-Trigger manufactured by Texas Instruments is a quad-input Schmitt-Trigger Inverters, meaning it is composed of four independent inverter gates, each with Schmitt-Trigger action on the input. Its high-impedance inputs provide maximum flexibility when processing multiple signals. It has two active-low inputs and two active-high inputs, and the inputs have Schmitt-Trigger action at all four stages, which guarantee hysteresis and improve noise immunity. Additionally, there are hysteresis levels, high-current outputs, and an open-drain output capability for expanded versatility. This device is designed to perform the logic functions of inverting buffer, and its operating voltage range is from 2V to 5.5V. It is 5x5 mm in size, and comes in a Quad-In-Line package.
