ENABLE AND DISABLE TIMES, 3-STATE OUTPUTS
NOTES: A. C_L includes probe and jig capacitance and is 50 pF for t_pd and t_en, 5 pF for t_dis.
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2
is for an output with internal conditions such that the output is high except when disabled by the output control.
C. All input pulses have the following characteristics: For C suffix, use the voltage levels indicated in parentheses ( ). PRR ≤ 1 MHz,
t_r = t_f ≤ 2 ns, duty cycle = 50%. For M suffix, use the voltage levels indicated in brackets [ ]. PRR ≤ 10 MHz, t_r and t_f ≤ 2 ns,
duty cycle = 50%.
D. When measuring propagation delay times of 3-state outputs, switch S1 is closed.
E. Equivalent loads may be used for testing.
