*Conditions for output transition testing are: VDD = 50 V, VCC = 5 V, R1 = 500 Ω, C1 ≤ 30 pF.
NOTE: Information present at an input is transferred
to its latch when the STROBE is high. A high CLEAR
input will set all latches to the output off condition
regardless of the data or STROBE input levels. A high
OUTPUT ENABLE will set all outputs to the off con-
tdition, regardless of any other input conditions. When
the OUTPUT ENABLE is low, the outputs depend on
the state of their respective latches.
