NXP 74HCT132D,653 与非施密特触发, HCT系列, 8输入, 4门, 25 mA, 4.5V至5.5V, SOIC-14
The 74HCT132D is a quad 2-input NAND Gate with Schmitt-trigger inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt-trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals.
