    This decoder/demultiplexer is designed for 1.65-V to 5.5-V V_CC operation.

    The SN74LVC1G19 is a 1-of-2 decoder/demultiplexer. This device buffers the data on input A and passes it to the outputs Y0 (true) and Y1 (complement) when the enable (E) input signal is low.

    This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
