NOTE:
1 When using open collector parts, the value of the pull-up resistor greatly af fects the value of the t PLH. For example, changing the specified
pull-up resistor value from 500Ω to 100Ω will improve the tPLH up to 50% with only a slight increase in the tPHL. However, if the value of the
pull-up resistor is changed, the user must make certain that the total IOL current through the resistor and the total IIL’s of the receivers does
not exceed the IOL minimum specification.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may af fect device reliability.
