Note 2: This is standard value shows the timing when the output is off,
and doesn't show hold time of data bus.
Hold time of data bus is different by capacitor volume and pull-up
(pull-down) resistance value.
Hold time of data bus is expressed in
t = –CR X ln (1 – VOL / VCC)
by a circuit of the right figure.
For example, when VOL = 0.2VCC, C = 30pF, R = 1k
, hold time
of output “L” level is
t = – 30pF X 1k
X ln (1 – 0.2VCC / VCC)
= 6.7ns.
