NOTES:
1. Upon customers request, up to 400 kHz (Max.) in standard mode and 1 MHz in fast mode are available.
2. When acting as a transmitter, the 24LLC08 must provide an internal minimum delay time to bridge the undefined
period (minimum 300 ns) of the falling edge of SCL. This is required to avoid unintended generation of a start or
stop condition.
* All specs and applications shown above subject to change without prior notice.
