Reading Datasheets: Output Currents (IOH and IOL)

DC characteristic #2: Output currents (I(OH) and I(OL))

DC characteristic #2: Output currents (IOH and IOL)

The drive capability of the output buffer and the guaranteed output current are important when connecting a CMOS logic IC with an LSI chip.

DC characteristics of the 74VHC04FT

Example: Output current (I(OH)/I(OL)) vs output voltage (V(OH)/V(OL)) curves of the 74VHC04

Example: Output current (IOH/IOL) vs output voltage (VOH/VOL) curves of the 74VHC04

CMOS logic ICs are designed to provide almost the same drive capability at both IOH and IOL.
