The specified limits shown can be met only after thermal equilibrium has been established. Thermal

equilibrium is established by applying power for at least two minutes while maintaining the normal operating

environment. (IBIAS = 1.2 mA, SLEWADJ = 2.5 mA)

Tpd is measured from crossover point of DHI and DHI* to the 50% point in the output. DVL

equals 0 V and DVH equals +3 V.

Specification condition: DVL equals -1 V and DVH equals +1 V. Output is terminated to GND by

100 Ω. Tpd is measured from the crossover point of DRVEN and DRVEN* to the point where a

10-percent change in output voltage occurs.

The driver load is an 18 cm 50Ω transmission line terminated with 1KΩ in parallel with 3 pF.

ECL output conditions. Signal reaches 100% of programmed value.

The output pulse width is measured at the 50-percent points. Output reaches 100% of programmed

value.
