LTC1326/LTC1326-2.5
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. LTC1326 Only VCC3 = 3.3V, VCC5 = 5V, VCCA = VCC3, TA = 25°C 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: All voltage values are with respect to GND.
Note 3: The output pins SRST and RST have weak internal pull-ups to
VCC3 of 6µA typ. However, external pull-up resistors may be used when
faster rise times are required.
Note 4: The VCC5 reset override voltage is valid for an operating range less
than approximately 4.15V. Above this point the override is turned off and
the VCC5 pin functions normally.
