NOTES:
1. For 3-State outputs; output enable times are tested with C
= 30pF to the 1.5V level, and S
is open for high-impedance to High tests and
closed for high-impedance to Low tests. Output disable times are tested with C
= 5pF. High-to-High impedance tests are made to an output
voltage of V
= (V
– 0.5V) with S
open, and Low-to-High impedance tests are made to the V
T
= (V
OL
+ 0.5V) level with S
1
closed.
2. All propagation delays are measured and specified under worst case conditions.
VOLTAGE WAVEFORM
MEASUREMENTS:
All circuit delays are measured at the +1.5V level
of inputs and outputs, unless otherwise specified.
