SCPS245C December 2012 – December 2018 TCA9517A
PRODUCTION DATA.
The TCA9517A has an active-high enable (EN) input with an internal pull-up to VCCB, which allows the user to select when the repeater is active. This can be used to isolate a badly behaved slave on power-up reset. The EN input should change state only when the global bus and repeater port are in an idle state, to prevent system failures.
