AC ELECTRICAL CHARACTERISTICS

The timing waveforms shown in this section are tested with the following values:

AC timing specifications that are referenced to a device input signal are measured

in production with respect to the VIH/VIL 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 VOL and VOH 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.

VIL maximum of 0.5 V

VIH minimum of 2.4 V for all pins

Note:

CLK, RESET, MODA, MODB, and MODC are tested using

the input levels described in DC Electrical

Characteristics on page 2-3.
