NOTES:
1. Typical values are for TA = 25oC and nominal VDD.
2. IOL = IOH = 1µA
3. Operating current is measured at 2MHz in an CDP1802 system with open outputs and a program of 6N55, 6NAA, 6N55, 6NAA,....
Dynamic Electrical Specifications At TA = -40oC to +85oC, VDD = ±5%, tR, tF = 20ns, VIH = 0.7 VDD, VIL = 0.3 VDD, CL = 100pF,
and 1 TTL Load
