Data sheet
Absolute Maximum Ratings
Absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†
Supply voltage, V_DD (see Note 1)
Supply current, I_DD (see Note 2)
Input voltage range, V_I (see Note 1)
Output voltage range, V_O (see Note 1)
Storage temperature range, T_A
–0.3 to 7 V
35 mA
–0.3 to VDD + 0.3 V
–0.3 to VDD + 0.3 V
–30°C to 125°C
WARNING:
Stressing the SC-614 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.
