Circuit Description (continued)
The comparator outputs are "Flex Out". They are technology
independent and may be adjusted over a wide voltage
common mode range. COMP HIGH and COMP LOW are
analog inputs which set the digital high and low levels
(respectively) of QA and QB. COMP HIGH and COMP LOW
are unbuffered inputs that provide the necessary drive
current, so the sources for these levels must have adequate
current capability.
Figure 4. Simplified Model of the
Unbuffered Comparator Output Stage
Typically, COMP HIGH and COMP LOW will be connected
to the digital power supplies of the chip receiving QA and
QB.
Receiver Headroom
There is ~3V of headroom required between the
comparator thresholds and both power supply levels.
