SN74LS132N NAND Schmitt triger

These devices contain four independent 2-input NAND gates in a DIP-14 through hole package. But because of the Schmitt action, the gates have different input threshold levels for positive (VT+) and negative (VT-) signals.Electrical CharacteristicsSupply voltage (VCC): 5 VHigh Level Input Voltage (VIH): 2 VHigh Level Input Current (IIH): 40 uALow Level Input Voltage (VIL): 0.8 VLow Level Input Current (IIL): -0.8 mAHigh Level Output Voltage (VOH): 3.4 VHigh Level Output Current (IOH): -0.8 mALow Level Output Voltage (VOL): 0.2 VLow Level Output Current (IOL): 16 mAOperating free-air temperature: 70C (max)Positive Threshold Voltage (VT+): 1.7 VNegative Threshold Voltage (VT-): 0.9 VPinoutHysteresis curveDocumentsDatasheet
