WARNING
:
Stressing the SC-604 beyond the “Absolute
Maximum Ratings” may cause permanent
damage. These are stress ratings only.
Operation beyond the “Operating Conditions” is
not recommended and extended exposure
beyond the “Operating Conditions” may affect
device reliability.
NOTES: 1. Unless otherwise noted, all voltages are measured with respect to V
SS
.
2. The total supply current includes the current out of all the I/O pins as well as the operating current of the device.
