The algebraic convention, where the more positive (less negative) limit is designated as maximum, is used in this data sheet for logic levels only (e.g., if –10 V is maximum, the typical value is a more negative voltage). 3. Output short-circuit conditions must maintain the total power dissipation below absolute maximum ratings. 4. Test conditions are those specified by EIA/TIA-232-E and as listed above. switching characteristics, VCC = 5 V, VDD = 12 V, VSS = –12 V, TA = 25°C PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tPLH Propagation delay time, low- to high-level output RL = 3 kΩ to 7 kΩ,CL = 15 pF, 315 500 ns tPHL Propagation delay time, high- to low-level output L , L , See Figure 3 75 175 ns tTLH Transition time low to high level output RL = 3 kΩ to 7 kΩ,CL = 15 pF, See Figure 3 60 100 ns tTLH Transition time, low- to high-level output RL = 3 kΩ to 7 kΩ, CL = 2500 pF, See Figure 3 and Note 5 1.7 2.5 µs tTHL Transition time high to low level output RL = 3 kΩ to 7 kΩ,CL = 15 pF, See Figure 3 40 75 ns tTHL Transition time, high- to low-level output RL = 3 kΩ to 7 kΩ, CL = 2500 pF, See Figure 3 and Note 6 1.5 2.5 µs NOTES: 5.
