AC Electrical Specifications
NOTES:
29. Asynchronous inputs are INTR, NMl, HOLD, PEREQ, ERROR, and BUSY. This specification is given only for testing purposes, to assure
30. Delay from 1.0V on the CLK to 0.8V or 2.0V.
31. Output load: C
32. Delay measured from address either reaching 0.8V or 2.0V (valid) to status going active reaching 0.8V or status going inactive reaching
33. Delay from 1.0V on the CLK to Float (no current drive) condition.
34. Delay from 1.0V on the CLK to 0.8V for min. (HOLD time) and to 2.0V for max. (inactive delay).
35. Delay from 1.0V on the CLK to 2.0V for min. (HOLD time) and to 0.8V for max. (active delay).
36. Delay from 1.0V on the CLK to 2.0V.
