ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VPVBATT = VSVBATT = 3.3V, DVCC = 3.3V, unless otherwise noted.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: This specication applies to all three smart card voltage classes:
1.8V, 3V and 5V.
Note 3: ROLCP (2VBATT – VCPO)/ICPO; VCPO will depend upon total load
(ICCA + ICCB) and minimum supply voltage VBATT. See Figure 5.

Note 4: The LTC1955E is guaranteed to meet performance specications
from 0°C to 85°C. Specications over the –40°C to 85°C operating
ambient temperature range are assured by design, characterization and
correlation with statistical process controls. The LTC1955I is guaranteed to
meet performance specications over the full –40°C to 85°C temperature
range.
