Product data sheet
OE must be held active LOW for at least the duration of the rise/fall time of the LEDn pins. This pulse width does not apply to
active LOW times for executing error detect sequences.
Timing required for signaling of error detection sequences. Not necessary for ‘normal’ operation.
