HD3SS3202: Using the HD3SS3202 with VCC=0V.

Uchida Yasuhide

Part Number: HD3SS3202

Hi,

In OFF mode, I would like to use the VCC voltage of the HD3SS3202 is 0V.

I have two questions.

Q1:When I continue to use the HD3SS3202 with VCC=0V, is there damage to the HD3SS3202 ?

Q2:When VCC is 0V, are differential signal ports(A0, A1, B0, B1, C0, C1) Hi-impedance?

Best Regards

Uchida:

Q1: if S pin is still high when Vcc is 0v, it will back drive the device and hurt device liability.

Q2, when Vcc is 0v, differential signal ports should be hi impedane.

Regards

Brian

Hi,

Thank you for your reply.

I have an additional question.

When I continue to use the HD3SS3202 with VCC=0V, SEL=0V, OEn=0V, is there damage to the HD3SS3202 ?

Best Regards

no damage if vcc and control pins are 0v.
