1Tested at 25°C. Specifications are assured by design and characterization over the operating temperature range of –40°C to 85°C.  
2Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions. Performance may vary for  
individual units, within the specified maximum and minimum limits.  
3Err = (IO(min or max) – IO(av)) / IO(av). IO(av) is the average current of all outputs. IO(min or max) is the output current with the greatest  
difference from IO(av).  
4Recommended operating range: VO = 1.0 to 3.0 V.  
SWITCHING CHARACTERISTICS at TA1 = 25°C, VDD = VIH = 5.0 V, VDS = 1 V, VIL = 0 V, REXT = 910 ꢀ, IO = 21.4 mA, VL = 2 V,  
RL = 51 ꢀ, CL = 15 pF (see also Timing Diagrams section)
