Output Optimized for 3V and 5V Supplies
LT1715 easy to use even with slow moving input signals.
n
TTL/CMOS Compatible Rail-to-Rail Output
The rail-to-rail outputs directly interface toTTL and CMOS.

pinout of the LT1715 minimizes parasitic effects by placing
the most sensitive inputs away from the outputs, shielded
by the power rails.
