Overview
The SN74LVC1G14DBVRE4, produced by Texas Instruments, is a single Schmitt-trigger inverter designed to operate within a voltage range of 1.65 V to 5.5 V. This device performs the Boolean function Y = A and is characterized by its ability to handle noisy or slow input signals due to its Schmitt-trigger inputs. The SN74LVC1G14 is fully specified for partial-power-down applications, utilizing Ioff circuitry to disable the outputs when the device is powered down, thereby preventing current backflow and potential damage to the device.
