Original question:

AM26LV32E: Input leakage to VCC and outputs when unpowered?

AM26LV32E: phenomenon during power off

Part Number: AM26LV32E

Hello Experts,

I would like to reconfirm a question of below thread.
https://e2e.ti.com/support/interface/f/138/t/933450

The AM26LV32EIPW will accepts the input signals with no abnormal behavior even if the device power is not present. (The datasheet stated Absolute Maximum Ratings at input pins (A&B) is +/-14V). Is my understanding correct?

Best Regards,
Fujiwara

    Fujiwara-san,

    I want to make sure I understand your question. To be clear, the device requires power to properly operate as a receiver - specifically a supply voltage VCC between 3 V and 3.6 V.

    The question you referenced was a discussion regarding the leakage currents experienced when the device is not powered. The high impedance of the device should limit backflow current while unpowered, if that is the concern.

    The datasheet stated Absolute Maximum Ratings at input pins (A&B) is +/-14V

    The ±14 V characteristic indicates that the device will not be damaged when the inputs A/B are within this range, even when VCC = 0.

    Do I understand your question properly?

    Best,

    Danny
