Electrical Characteristics (over Operating Temperature)
Notes
1.
Peak current=1.87 X ILL. ILL varies with VLL Normalized curve, Figure 11.
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.
