SN65DP159: Pullup / Pulldown resistor of Control pins

Jim CHEN

Part Number: SN65DP159

Dear Team,

In the datasheet, it use 65k ohm pullup/ pulldown resistor for the control pins.

My customer would like to use 60.4k ohm resistor. Is it ok?

What is the tolerance requirement?

Thank you.

Jim.

Resistor tolerance is 65k +/- 10%.

Thanks

Hi David,

I just confirmed with Win this week. He said 65K ohm resistor for pullup and pulldown resistor is for mid-level.

But if the customer doesn't use mid-level for control pins, 10k ohm should be fine for high-level and low-level.

Thank you.

Please see the note in the datasheet:

(H) Logic high (pin strapped to VCC through 65-kΩ resistor); (L) logic low (pin strapped to GND through 65-kΩ resistor); (for mid-level, no connect).

Thanks

David
