AM26LV32E: Output Conditions

Part Number: AM26LV32E

Hi,

If G LOW and G_Bar HIGH, will the output be LOW with an input at any state?

Also are you aware of similar receiver which keep the outputs LOW if and when the inputs are floating?

Thank you,

HSG

    Hello HSG,

    Thanks for bringing this question to E2E. If G is low and G_bar is high, the output will be high-impedance, so with a discharge path it will be low, unless something is externally pulling it up.

    I am not aware of similar devices that keep the outputs low if the inputs are floating, typically the outputs are held high when the inputs are left floating. I've notified our RS485 and RS232 expert of this thread so he can comment further.

    Regards,

    HSG,

    I'm not aware of any RS-485 transceivers keep the output active low with floating input. The reason is that the driver usually is disabled by default to minimize the disturbance to the bus when the device is hot plugged in.

    Regards,
