Operation (Continued)
The high and low output levels of the CLC005 are set by a
circuit shown simplified in
Figure 8. Output high and low lev-
els may be set independently with external resistor networks
connected between R
EXT-H (pin 3), REXT-L (pin 4) and the
power supplies. The resistor networks affect the high and
low output levels by changing the internally generated bias
voltages, V
H and V L. The nominal high and low output levels
are V
CC−1.7V and VCC−3.7V, respectively, when the pins
EXT-H and REXT-L are left unconnected. Though the internal
components which determine output voltage levels have ac-
curate ratios, their absolute values may be controlled only
within about ±15% of nominal. Even so, without external ad-
justment, output voltages are well controlled. A final design
should accommodate the variation in externally set output
voltages due to the CLC005’s part-to-part and external com-
ponent tolerances.
Output voltage swing may be reduced with the circuit shown
Figure 9. A single resistance chosen with the aid of the
Figure 10, is connected between pins 3 and 4. Output
voltage swing may be increased with the circuit of
Figure 11.
Figure 12 is used to estimate a value for resistor R. Note that
both of these circuits and the accompanying graphs assume
that the CLC005 is loaded with the standard 150
Ω. Be aware
that output loading will affect the output swing and the high
and low levels. It may be necessary to empirically select re-
sistances used to set output levels when the D.C. loading on
the CLC005 differs appreciably from 150
