MSM80C85AHRS/GS/JS

Notes: (1) A8 - A15 address Specs apply to IO/M, S0 and S1.

(2) Test condition: tCYC=200 ns CL=150 pF

(3) For all output timing where CL=150 pF use the following correction factors:

25 pF £ CL < 150 pF : –0.10ns/pF

150 pF < CL £ 200 pF : +0.30ns/pF

(4) Output timings are measured with purely capacitive load.

(5) All timings are measured to output voltage VL=0.8 V, VH=2.2 V, and 1.5 V

with 10 ns rise and fall time on inputs.

(6) To calculate timing specifications at other values of tCYC use Table 7.

(7) Data hold time is guaranteed under all loading conditions.
