LTC4300A-1/LTC4300A-2
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
Guaranteed by design, not subject to test. may cause permanent damage to the device. Exposure to any Absolute
Note 5:
CB = total capacitance of one bus line in pF. Maximum Rating condition for extended periods may affect device
Note 6:
These tests measure the difference in high-to-low propagation reliability and lifetime. delay tPHL between the clock and data channels. The delay on each
Note 2:
IPULLUPAC varies with temperature and VCC voltage, as shown in channel is measured from the 50% point of the falling driven input signal the Typical Performance Characteristics section. to the 50% point of the output driven by the LTC4300A-1/LTC4300A-2.
Note 3:
The connection circuitry always regulates its output to a higher The skew is defined as (tPHL(SCL) – tPHL(SDA)). Testing is performed in voltage than its input. The magnitude of this offset voltage as a function of both directions—from input bus to output bus and vice versa. Tests are the pull-up resistor and VCC voltage is shown in the Typical Performance performed with approximately 500pF of distributed equivalent capacitance Characteristics section. on each SDA and SCL pin.
