Overview
The SN74LVC14ADRG3, produced by Texas Instruments, is a hex Schmitt-trigger inverter integrated circuit. This device is part of the SN74LVC14A series and is designed to operate within a wide voltage range of 1.65 V to 3.6 V. It contains six independent inverters, each performing the Boolean function Y = A. The SN74LVC14ADRG3 is particularly useful in mixed 3.3-V or 5-V system environments due to its ability to accept input voltages up to 5.5 V and its compatibility with both 3.3-V and 5-V devices.
