Dear Team:
When SN74LVC1G3157 is power off, and B1 is high, do we have leakage current/ voltage on pin A, B2, ?
Customer measured around 0.8V on A and B2 pin.
If yes,, do we have another chip that don't have this kind of leakage current.
Thomas,
If the SN74LVC1G3157 power supply Vcc = 0V we cannot guarantee that the part will be HI-Z state isolating the switch. It is possible you could have leakage if the device is powered off. If you need this function to have the switch isolate in a HI-Z state when Vcc = 0V you need to find a device that has powered off isolation feature. Currently on TI.com the parametric search labels this additional feature as Ioff or Ioff protection.
What do you think about using the TS5A12301E which has powered off isolation feature. Devices with this feature will have a leakage spec when Vcc = 0V
Thank you,
Adam
