AC ELECTRICAL CHARACTERISTICS
The timing waveforms shown in this section are tested with the following values:
V_IL maximum of 0.5 V
V_IH minimum of 2.4 V for all pins¹
Note:
1. CLK, RESET, MODA, MODB, and MODC are tested using
the input levels described in DC Electrical
Characteristics on page 2-3.
AC timing specifications that are referenced to a device input signal are measured
in production with respect to the V_IH/V_IL levels of the respective input signal’s
transition.
AC timing specifications that are referenced to a device’s output levels are
measured with the production test machine V_OL and V_OH reference levels set at
0.8 V and 2.0 V, respectively. For load capacitances greater than 50pF, the drive
capability of the output pins derates linearly at 1.5 ns per 20 pF of additional
capacitance from 50 pF to 200 pF of loading, and at 2 ns per 20 pF of additional
capacitance for loads greater than 200 pF.
