Effects of External Resistors on One-Shots

As shown in Rise and Fall Time Estimates With or Without the One-Shots, additional resistors will impact the rise and fall times, and the overall data throughput. To further avoid divider networks, careful considerations should be taken while choosing external resistors as the devices are mostly designed with internal resistors placed by the I/O pins. If external pull-ups and pull-downs are used, their value as well as accurate timing and temperature coefficients should also be considered. For more information, see Effects of Pullup and Pulldown Resistors on TXS and TXB Devices application note.
