NOTES: A. CL = 50 pF for TLC548 and 100 pF for TLC549; CL includes jig capacitance.
B. ten = tPZH or tPZL, tdis = tPHZ or tPLZ.
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.
