operation of the device at these or any other conditions
above those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect reliability.

Note:
[1] This specification applies over the full operating temperature range.
[2] The enable time can slow considerably for some parts when temperature is < −20 °C.
[3] Delays that can occur after ENABLE and/or idle times have passed.
[4] Guaranteed by design, not production tested.
[5] Itrt(pu) varies with temperature and VCC voltage.
[6] Input pull-up voltage should not exceed power supply voltage in operating mode because the rise time accelerator will
clamp the voltage to the positive supply rail.
[7] The connection circuitry always regulates its output to a higher voltage than its input.
[8] Force VSDAIN = VSCLIN = 0.1 V, tie SDAOUT and SCLOUT through 10 kΩ resistor to VCC and measure the SDAOUT and
SCLOUT output.

Remark: The PI6ULS5V9511A can be used in any combination depending on the number of rise time
accelerators that are needed by the system. Normally only one PI6ULS5V9511A would be required per bus.
