Other Parts Discussed in Thread: SN74LV4066A
I want to use 4 IC I2C DAC LTC2616 using the same I2C of the microcontroller.
In order to save power consumption I will place a power switch for each one VCC Power.
This is the comment form the datasheet of LTC2616 "The VCC power should not be removed
from the LTC2606/LTC2616/LTC2626 when the I2C bus is active to avoid
loading the I2C bus lines through the internal ESD protection diodes."
Can I use PCA9546A for this purpose in order to be able to eliminate the power of the IC LTC2616?
Case of use:
- One I2C of microcontroller connect to the port I2C of the 4 IC LTC2616
- 4 Power switches for the VCC of the LTC2616
I attach a block diagram from my system:
- Power Diagram
Possible communications diagram
If PCA9546A isn't a good fit which IC might fit in my application.
