ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions 2.7V ≤ VIN ≤ 5.5V, -20°C ≤ TA ≤ 85°C, GND = 0V, unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.

Notes
10. Guaranteed by Design
11. Available only on the 34704A
12. When battery voltage is higher than 5.0V, a diode implementation like the one displayed on VG is necessary.
