DM74LS139 Recommended Operating Conditions

DM74LS139 Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted)

Note 6: All typicals are at VCC = 5V, TA = 25°C.

Note 7: Not more than one output should be shorted at a time, and the duration should not exceed one second.

Note 8: ICC is measured with all outputs enabled and OPEN.
