DM74ALS109A
Electrical Characteristics
over recommended operating free-air temperature range. All typical values are measured at V
CC
= 5V, T
A
= 25°C.
Note 4: The output conditions have been chosen to produce a current that closely approximates one half of the true short circuit output current, I
OS
.
Note 5: I
CC
is measured with J, K, CLK and PRESET grounded, then with J, K, CLK and CLEAR grounded.
