Part Number: SN75437A
Other Parts Discussed in Thread: ULN2003A

Hello Team,

My customer would like to know if we have a guide on using the SN75437A device on Solenoid? or a guide on how they will wire the load on SN75437A?

Regards,

Renan

    Hi Renan,

    Due to the age of this device, collateral surrounding it is limited.

    This is a low side switch and so connecting it up would be similar to other multi channel low side switches like ULN2003A.

    The control signals are to be sent to the "A" pins while the "G" pin is a global enable pin.

    The solenoid must be connected to the respective "Y" pins.

    When the "A" pin and "G" pin are pulled high, the channel conducts and connects the solenoid input to GND
