Overview
The SN74LVC1G14DBVRG4, produced by Texas Instruments, is a single Schmitt-trigger inverter designed for a wide range of voltage operations from 1.65 V to 5.5 V. This device performs the Boolean function Y = A, making it an independent inverter with Schmitt-trigger inputs. The Schmitt-trigger inputs provide hysteresis, which makes the device tolerant to slow or noisy input signals. The SN74LVC1G14 is fully specified for partial-power-down applications, featuring Ioff circuitry that disables the outputs when the device is powered down, preventing current backflow and potential damage to the device.
