TS5A3160: - Question about connection and usage

Part Number: TS5A3160

Hi,

Regarding with connection of TS5A3160, I would like to know whether it can be used as both cases below? The reason I would like to ask is because, pin function description mention that NO (Pin 1), NC (Pin 3) and COM (Pin 4) are Input/Output pins. For simplicity, I did not show GND pins, V+ pin and IN pins connections.

(A) Source is connected to COM (Pin 4) and depending on IN (Pin 6) logic level, either load 1 or load 2 will be given power coming from COM pin.

(B) Source 1 and Source 2 are connected to NO (Pin 1) and NC (Pin 3) respectively, and depending on IN (Pin 6) logic level, load will be given power by either source 1 or source 2.

Lastly, if TS5A3160 cannot achieve both, then, is there any other alternative IC to achieve both case A and B?

Thank you.

Regards,

LB

    LB,

    The TS5A3160 is a low power signal switch that is bi-directional and will connect the common pin (COM) to the Normally Open (NO) or Normally Closed (NC) pin based on the voltage applied to the control logic.  This means it will work for both cases A and B as long as you operate within the recommended conditions. 

    Since you mention applying power to loads you must keep the current through the switch <200mA

    In example B you also need to make sure that the device you use has the break before make feature so that you do not short your two supplies together. 

    The switches and multiplexers FAQ page is also great for more information on the usage of these devices.

    Thank you,

    Adam
