NOTES:

1. Maximum limits of minimum characteristics are the values above which all devices function.

2. Typical values are for TA = 25

oC and nominal voltages.

Dynamic Electrical Speciﬁcations At TA = -40 to +85oC, VDD ±5%, tR, tF = 20ns, VIH = 0.7VDD, VIL = 0.3VDD,

CL = 100pF (See Figure 9) (Continued)
