Notes  
1. Not including current drawn from the FX489 pins by external circuitry. See Absolute Maximum Ratings.  
2. For V in the range V to VDD.  
3
For aINload of 10korSgSreater. Tx PS input at logic “0”; Tx Enable = “1”.  
4. Data pattern of “1111000011110000 ..”  
5. Measured between the rising edge of ‘Tx Clock’ and the centre of the corresponding bit at ‘Tx Out.’  
6. Time between the falling edge of ‘Tx PS’ and the ‘Tx Out’ voltage stabilising to normal output levels.  
7. For a load of 10kor greater. Rx PS input at logic “0”.  
8. For optimum performance, measured at the ‘Rx Feedback’ pin for a “1111000011110000 ...” pattern.  
9. Measured between the centre of bit at ‘Rx Signal In’ and corresponding rising edge of the ‘Rx Clock’.  
10. Timing for an external clock input to the Xtal/Clock pin.
