Overview
The SN74LVC2G04DCKTG4, produced by Texas Instruments, is a dual inverter gate designed for operation over a wide voltage range of 1.65 V to 5.5 V. This device is part of the LVC (Low-Voltage CMOS) family and is known for its low power consumption and high-speed operation. The SN74LVC2G04 contains two identical inverters, each capable of performing the Boolean function Y = A. It features overvoltage tolerant inputs, allowing for down-translation of logic levels, and supports partial-power-down mode operation to prevent damaging current backflow when the device is powered down.
