The SN74LVC14A SN74LVC14A contains six independent inverters, and performs the Boolean function Y = A. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. The SN74LVC14A SN74LVC14A is characterized for operation from 40°C to 85°C.
