Hi all.

SN75DP130SS is defined the power up sequence(for example : required 100us between RSTN and Vcc power up timming),
but power down sequence is not defined timming.(Figure 34 )
Is this device have the specified value of power down?
And does this device have EN low timing?

I think power down sequence of SN75DP130SS is RSTN→Vcc only.
Is this my understand currect?

Hi Yusuke,

Power down sequence is RSTN --> Vcc only, there are not timing requirements.

Hi Moises san

Thank you for your response.
I understood power down sequence is RSTN→Vcc only.

I have two questions.
1. Please give reference circuits of RSTN pin and EN pin.
2. Is EN unconserned power up and power down sequense?

Best Regards,
Yusuke
