4-INPUT / 4-OUTPUT DUAL ANALOG SWITCH
GENERAL DESCRIPTION PACKAGE OUTLINE
The NJU72751 is a 4-input / 4-output dual analog switch.
Functions are controlled via two-wired serial bus. A-channel
switches and B-channel switches are controlled independently.
The NJU72751 is well-suited for multi-channel audio systems
such as AV amplifiers, DVD receivers and others.
FEATURES
Operating Voltage ±4.5 to ±7.5V
2-wired Serial BUS Control
Selectable 2-Chip Address Available for using four chips on same serial bus line
