Note 1: All typicals are at V CC e 5V, T A e 25 § C.
Note 2: Not more than one output should be shorted at a time, and the duration should not exceed one second.
Note 3: I CCH is measured with all outputs open, one input at each gate at 4.5V, and the other inputs grounded.
Note 4: I CCL is measured with all outputs open and all inputs grounded.
