74系列逻辑芯片/74LVC1G06GV
Inverter with open-drain output;The 74LVC1G06 provides the inverting buffer. Input can be driven from either 3.3 V or 5 V devices. These features allow the use of these devices in a mixed 3.3 V and 5 V environment. Schmitt-trigger action at all inputs makes the circuit tolerant for 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. The output of the device is an open drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
