CL = 5pF : tOEN, tODIS

Input pulse level

: 0 – 3V

Input pulse up/down time : 3 ns

Judging voltage Input

: 1.3V

Output

: 1.3V(However, tODIS(LZ) is judged with 10% of the

output amplitude, while tODIS(HZ) is judged with

90% of the output amplitude.)

Load capacitance CL includes the floating capacity of connected lines and input

capacitance of probe.
