Nexperia 74LVC1G19GW,125

The 74LVC1G19 is a 1-of-2 decoder/demultiplexer with a common output enable. This device buffers the data on input A and passes it to the outputs 1Y (true) and 2Y (complement) when the enable (E) input signal is LOW. A HIGH E causes both outputs to assume a HIGH state. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows 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 of slower input rise and fall times. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
