Electrical characteristics (over operating temperature)
Notes:
1) Peak current 5/3 x I
CC.
2) Unused inputs must be tied high.
3) Contact Siemens for 3.3 volt operation.
4) External oscillator must be stopped if being used to maintain an I
CC<50 A.
Input/Output Circuits
Figures 4 and 5 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.
