DSP56166 Technical Data Sheet

MOTOROLA

DC Electrical Characteristics (VSS = 0 Vdc)

(Vdd = 5.0 Vdc +/- 10%, TJ = -40 to +125

°C, CL = 50 pF + 1 TTL Load).

The DC electrical characteristics of this device are shown below.

NOTES:

1. When EXTAL is AC coupled, VIHC - VILC

≥1V must be true.

2. Input capacitance is periodically sampled and not 100% tested in production.
