NJU72750A
7-INPUT / 3-OUTPUT DUAL ANALOG SWITCH
GENERAL DESCRIPTION
The NJU72750A is a 7-input / 3-output dual analog switch.
Functions are controlled via two-wired serial bus. A-channel
switches and B-channel switches are controlled independently.
The NJU72750A is well-suited for multi-channel audio systems
such as AV amplifiers, DVD receivers and others.
