21 AC CHARACTERISTICS
See notes 1 and 2; CL = 100 pF for Port 0, ALE and PSEN; CL = 80 pF for all other outputs unless otherwise specied.
Notes
1. For the AC Characteristics the following conditions are valid:P8xCE598 FxB:
VDD =5V ± 10%; Tamb = 40 to +85 °C (125 °C); fCLK = 1.2 to 16 MHz.
2.
; tCLK = 62.5 ns at fCLK = 16 MHz.
