(1)

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.

(2)

Additional quiescent supply current per input pin, TTL inputs high, 1 unit load.
