NOTES: A. Input pulses are supplied by generators having the following characteristics: PRR
≤ 1 MHz, ZO ≈ 50; for SN54/74221, tr ≤ 7 ns,
tf ≤ 7 ns, for SN54/74LS221, tr ≤ 15 ns, tf ≤ 6 ns.
B. 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.
