The SN74LVC1G14DCKT from Texas Instruments is a single Schmitt-trigger inverter in an SC-70-5 (DCK) package. Operating from 1.65V to 5.5V, it performs the Boolean function Y = NOT(A) with hysteresis on the input, providing excellent noise immunity for slow or noisy signals. The device features 4.6 ns max propagation delay at 3.3V and Ioff partial-power-down support.<\/p>\n

The Schmitt-trigger input architecture provides different threshold levels for positive-going (VT+) and negative-going (VT-) signals, creating hysteresis (delta-VT) that makes the device tolerant to slow or noisy input transitions. The device performs the Boolean function Y = NOT(A) and is fully specified for partial-power-down applications using Ioff. The DCK (SC-70-5) package offers a compact footprint for space-constrained designs.","working_principle":"The SN74LVC1G14 contains a single inverting buffer with Schmitt-trigger inputs. The input stage has two switching thresholds: a higher VT+ for rising signals and a lower VT- for falling signals. The difference (VT+ minus VT-) is the hysteresis voltage, which prevents output oscillation when the input signal slowly traverses the switching region or has noise superimposed. The CMOS push-pull output stage provides balanced +\/-24 mA drive at 3.3V. The Ioff circuitry disables the output when VCC is 0V, preventing backflow current during partial-power-down conditions and supporting live insertion.","pin_description":"
