NOTES: A. CL includes probe and jig capacitance.
B. All diodes are 1N3064 or equivalent.
C. In the examples above, the phase relationships between inputs and outputs have been chosen arbitrarily.
D. All input pulses are supplied by generators having the following characteristics: PRR
≤ 1 MHz, ZO ≈ 50 and, for SN54/74221,
tr ≤ 7 ns, tf ≤ 7 ns, for SN54/74LS221, tr ≤ 15 ns, tf ≤ 6 ns.
E. All measurements are made between the 1.5-V points of the indicated transitions for the SN54/74221 or between the 1.3-V points
for the SN54/74LS221.
