The ALVC132 contains four 2-input NAND gates with Schmitt Trigger Inputs. The pin configuration and function are the same as the ALVC00 except the inputs have hysteresis between the positive-going and negative-going input thresholds. This hysteresis is useful for transforming slowly switching input signals into sharply defined, jitterfree output signals. This product should be used where noise margin greater than that of conventional gates is required.
