Hello,

My customer has a question about LMH0074.

[Q]

They are going to use with low for BYPASS pin.

Please tell me your recommendation value for the pull-down resistor.

Greetings,

Maximum input low voltage is 0.8V. If the customer has FPGA driving this pin, then we must make sure we don't go over 0.8V. If this is going to be controlled by pin, then 1K Ohm resistor should be good. This provides enough isolation in a case there is noise on the ground plane.
