NOTE: I/O PIN DATA IS NOT LATCHED
I/O as Output
NOTES:
1. INCLUDES I/O WHEN USED AS TxRDY or RxDY/FFULL OUTPUTS AS WELL AS IRQN.
2. THE TEST FOR OPEN DRAIN OUTPUTS IS INTENDED TO GUARANTEE SWITCHING OF THE OUTPUT TRANSISTOR. MEASUREMENT OF THIS RESPONSE IS
REFERENCED FROM THE MIDPOINT OF THE SWITCHING SIGNAL, V
SURES TRUE SWITCHING HAS OCCURRED. BEYOND THIS LEVEL, THE EFFECTS OF EXTERNAL CIRCUITRY AND TEST ENVIRONMENT ARE PRONOUNCED
AND CAN GREATLY AFFECT THE RESULTANT MEASUREMENT.
