ZHCSIF1A June 2018 – February 2022 TCA9517-Q1
PRODUCTION DATA
The TCA9517-Q1 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 target 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.
