Electrical Characteristics at 25

°C

Notes:

1) When an external clock is used it must be stopped.

2) Unused inputs must be tied high.

3) Peak current 5/3 xICC.

Input/Output Circuits

Figures 5 and 6 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.
