SN74HC244: Absolute max rating for input and output, IoL and IoH

Part Number: SN74HC244

Hi Expert,

Could you please let me know about the spec of Absolute max rating for input and output, IoL and IoH?

SN74HC244 don't have those specs.

SN74LV244A datasheet



  • HC devices have no voltage ratings because all I/O pins are diode-clamped to the power rails. The only limit is the input/output clamp current, IxK.

    The recommended IOL/IOH limits can be found in the test conditions of the electrical characteristics. (If you exceed these limits, the electrical characteristics are no longer guaranteed.)
