DC Electrical Characteristics (Continued)

Note 4: These are peak output current capabilities. Continuous output current is rated at 12 mA maximum. The output current should not be allowed to

exceed this value for extended periods of time. IOL and IOH are tested one output at a time.

AC Electrical Characteristics (Note 5)

CD4049UBC

TA = 25°C, CL = 50 pF, RL = 200k, tr = tf = 20 ns, unless otherwise specified

Note 5: AC Parameters are guaranteed by DC correlated testing.

AC Electrical Characteristics (Note 6)

CD4050BC

TA = 25°C, CL = 50 pF, RL = 200k, tr = tf = 20 ns, unless otherwise specified

Note 6: AC Parameters are guaranteed by DC correlated testing.
