NOTES: A. CL includes probe and jig capacitance and is 50 pF for tpd and ten, 5 pF for tdis.
B. All input pulses have the following characteristics: For C suffix, PRR
1 MHz, tr = tf = 2 ns, duty cycle = 50%; For M suffix,
PRR
10 MHz, tr = tf
2 ns, duty cycle = 50%
C. 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.
D. When measuring propagation delay times of 3-state outputs, switch S1 is closed.
E. Equivalent loads may be used for testing.
