5. Key Advantages
 Low quiescent current: 100µA typical for 47ns
propagation delay
 So What: Low quiescent current is ideal for battery applications.
The high speed makes these comparators attractive in a wide
variety of applications.

6. Key Advantages
 Low voltage operation (1.8V) with Rail-to-Rail
Input/Output
 So What: 1.8V operation allows two dry cells to be drained well
beyond typical use. (1.8V is the 90% drained level.) Rail to rail
allows full range use even in low supply conditions.

7. Key Advantages
Small Packaging (SOT-23, SC-70)
 So What: The combination of small packaging, low quiescent
current and low operating voltage make these comparators ideal
for portable applications where PCB size is limited.
