OUTPUT INTERFACING
The CLC007’s class AB output stage, Figure 6, requires no
standing current in the output transistors and therefore re-
quires no biasing or pull-down resistors. Advantages of this
arrangement are lower power dissipation and fewer external
components. The output may be either D.C. or A.C. coupled
to the load. A bandgap voltage reference sets output voltage
levels which are compatible with F100K and 10K ECL when

correctly terminated. The outputs do not have the same out-
put voltage temperature coefficient as 10K. Therefore, noise
margins will be reduced over the full temperature range when
driving 10K ECL. Noise margins will not be affected when in-
terfacing to F100K since F100K is fully voltage and tempera-
ture compensated.
