for low voltage operation. Separate supplies allow inde-

pendent analog input ranges and output logic levels with

no loss of performance. The input voltage range extends

esis makes the LT1715 easy to use even with slow moving

input signals. The rail-to-rail outputs directly interface to

TTL and CMOS. The symmetric output drive results in

similar rise and fall times that can be harnessed for analog

applications or for easy translation to other single supply

logic levels.

The LT1715 is available in the 10-pin MSOP package. The

pinout of the LT1715 minimizes parasitic effects by plac-

ing the most sensitive inputs away from the outputs,

shielded by the power rails.

For a dual/quad single supply comparator with similar

propagation delay, see the LT1720/LT1721. For a single

comparator with similar propagation delay, see the LT1719.
