SN74ACT14NS Texas Instruments

The SN74ACT14NS is a high-speed, quadruple Schmitt-trigger inverter manufactured by Texas Instruments. It is designed with Schmitt-trigger action to provide improved noise immunity when switching digital signals. This inverter generally works with 4 independent Schmitt-trigger circuits, each of which has two input thresholds - one for positive-going signals and one for negative-going signals. When an input signal approaches either the positive or negative threshold, the device switches state. The output remains in the same state until the input toggles out of the active threshold range and forces the output to switch states. This device is designed for use in high-speed data transmission systems and has a maximum propagation delay of 8ns, making it suitable for fast operation in high-speed circuit applications. It operates over a wide supply voltage range (2V to 5.5V) and temperature range (-55°C to 125°C). The SN74ACT14NS is widely used in SN systems, memory, timing, logic, and interface applications.
