output is off, and does not show hold time of
data bus.
Hold time of data bus varies with capacitor volume
and pull-up (pull-down) resistance value.
Hold time of data bus is expressed in
t = – CR ✕ ln (1 – V
by a circuit of the right figure.
For example, when V
R =1 kΩ, hold time of output “L” level is
t = – 30 pF ✕ 1 kΩ ✕ ln (1 – 0.2 V
