PARAMETER MEASUREMENT INFORMATION (continued)
NOTE: C
L
includes probe and jig capacitance. tpv is measured from 0.7 × V
CC
on SCL to 50% I/O (Pn) output. All inputs are
supplied by generators having the following characteristics: PRR ≤ 10 MHz, Z
O
= 50 Ω, t
r
/t
f
≤ 30 ns. The outputs are
measured one at a time, with one transition per measurement. All parameters and waveforms are not applicable to all
devices.
