Other Parts Discussed in Thread: SN751178

Hi Team,

Is there absolute maximum ratings of appling external voltage for output pin?
My customer wants to know if applying 5V to 1Y(14 pin) or 1Z(13 pin) could damage the device.
I heard he mistaked to apply 5V to output pin.

Best Regards,

Kensuke san,

Is the 5V the same 5V that is used for the VCC pin?

Kensuke-san,

If the output pin is programmed to be high then there won't be any stress to the SN751178.

If the output pin is programmed to be low then there will be high stress to the SN751178.
The current is limited but the dissipated power will overheat the device.
