DC Characteristics
Table 3: ECL Inputs and Outputs
(Over recommended operating conditions with internal V
REF,
V
CC
= GND, output load = 50
to -2.0V).
Note: Differential ECL output pins must be terminated identically.
Table 4: Power Dissipation
(Over recommended operating conditions, V
CC
= GND, outputs open circuit)
Table 5: High-Speed Input and Output Specifications
(Over recommended operating conditions, V
CC
= GND, output load = 50
to -2.0V)
NOTES: (1) Built-in references generator, the high-speed inputs are designed for AC-coupling.
(2) If a high-speed input is driven single-ended, a capacitor should be connected between the unused high-speed or complement
input and V
TT
(see Figures 7 and 8).
