PDF datasheet for the SN7414N, the TTL hex inverter with Schmitt-trigger inputs, supplied in a plastic DIP package as indicated by the N suffix. Hysteresis on its inputs makes it a common choice for cleaning up slow or noisy edges, debouncing switches and simple oscillators. The sheet is useful for checking threshold voltages, pin assignment and supply requirements while diagnosing a dead logic stage. Any standard PDF reader opens it; confirm the package marking against the part on the board first.
