Overview
The SN74LVC1G14DSFR, produced by Texas Instruments, is a single Schmitt-trigger inverter designed for operation within a voltage range of 1.65 V to 5.5 V. This device performs the Boolean function Y = A, functioning as an independent inverter with Schmitt-trigger inputs. The Schmitt-trigger inputs provide hysteresis, making the device tolerant to slow or noisy input signals. The SN74LVC1G14DSFR is available in a 6-SON (1x1) package and is fully specified for partial-power-down applications using Ioff circuitry, which disables the outputs when the device is powered down to prevent damage.
