The NJM2753 is 3-Input / 1-Output Stereo Audio Selector.
The NJM2753 consists of switches and buffer operational
amplifiers.
Based on the internal switch op-amp technology, the
NJM2753 features lower output noise, lower distortion and
higher channel separation than the general Multiplexers or
Analogue Switches.
The NJM2753 contains compatibility with NJM2752(2in-1out
SW),NJM2755(4in-1out SW).
