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). 6. Output short-circuit conditions must maintain the total power dissipation below absolute maximum ratings. 7. Test conditions are those specified by TIA/EIA-232-F 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, See Figure 3 315 500 ns tPHL Propagation delay time, high- to low-level output RL = 3 kΩ to 7 kΩ, CL = 15 pF, See Figure 3 75 175 ns tTLH Transition time, 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 8 1.7 2.5 µs tTHL Transition time, 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 8 1.5 2.5 µs NOTE 8: Measured between ±3-V and ±3-V points of the output waveform (TIA/EIA-232-F conditions); all unused inputs are tied either high or low. |
