三重反相施密特触发器具有5 V容限输入 Triple inverting Schmitt trigger with 5 V tolerant input
General description
The 74LVC3G14 provides three inverting buffers with Schmitt trigger action. The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment. Schmitt trigger action at the inputs makes the circuit tolerant of slower input rise and fall time. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
