General Description

The MAX9686 (single)/MAX9698 (dual) are very fast

TTL comparators manufactured with a high-frequency

short propagation delays, yet maintain the excellent DC

matching characteristics that are normally found only in

slower comparators. The MAX9698 is a dual version of

the MAX9686.

The MAX9686/MAX9698 have differential inputs and

complementary outputs that are fully compatible with

TTL logic levels. The extremely short propagation

delays allow signal processing at frequencies in excess

of 200MHz.

When the latch enable input goes high, the outputs go

to the states defined by the input condition at the time

of the latch transition. The outputs remain latched as

long as the LE pin remains high. If the latch enable

function is not used, the LE pin must be tied to ground.
