T8531/T8532 Multichannel Programmable
Timing Characteristics
A signal is valid if it is above V
IH
or below V
IL
and invalid if it is between V
IL
and V
IH
. For the purposes of this spec-
ification, the following conditions apply:
I
All input signals are defined as V
IL
= 0.4 V, V
IH
= 2.7 V, tR < 10 ns, tF < 10 ns.
I
tR is measured from V
IL
to V
IH
. tF is measured from V
IH
to V
IL
.
I
Delay times are measured from the input signal valid to the output signal valid.
I
Setup times are measured from the data input valid to the clock input invalid.
I
Hold times are measured from the clock signal valid to the data input invalid.
I
Pulse widths are measured from V
IL
to V
IL
or from V
IH
to V
IH
.
