SN74AUC1G86 Series Damping Resistor Value = ? Need to know to properly match trace impedance to device output.
Hi Keith,
This device does not have an integrated series damping resistor.
For calculating/estimating output resistance, please refer here: https://e2e.ti.com/support/logic-group/logic/f/logic-forum/718814/faq-what-is-the-output-transition-rate-for-a-logic-device
Best,
Malcolm
AUC outputs dynamically change their impedance during different stages of the switching, so a single series resistor would not work and should not be necessary. See section 2.1 of the AUC application report.
