Electrical Characteristics (over operating temperature)
Notes:
1) Peak current=1.87 x I
LLx ILL varies with VLL Normalized curve, Figure 12.
2) Unused inputs must be tied high.
3) Mux rate=[OSC Frequency/(64 x 7)].
4) External oscillator must be stopped during power down mode for minimum current.
Input/Output Circuits
Figures 3 and 4 show the input and output resistor/diode
networks used for ESD protection and to eliminate substrate
latch-up caused by input voltage over/under shoot.
