Test one output at a time, not exceeding 1-second duration. Measurement is made by forcing indicated current and measuring voltage

to minimize power dissipation. Test verifies a minimum 50-Ω transmission-line drive capability at 85°C and 75-Ω transmission-line drive

capability at 125°C.

4.6 Switching Characteristics, VCC = 1.5V

over recommended operating free-air temperature range, VCC = 1.5V, CL = 50pF (unless otherwise noted) (see Load Circuit
