Part Number: SN74LVC1G17-Q1
Other Parts Discussed in Thread: SN74LVC1G17

Hi team,

My customer asks question about output status of SN74LVC1G17 when Vcc is not supplied or open fault occurs in Vcc port.

Could you show if output will be open or short or gnd status in this case?

best regards,

When V_CC is at 0 V, all I/Os are high impedance.

When V_CC is open, there might still be a charge on the decoupling capacitors, so the device might still be powered.
