MAX9698

The MAX9686 (single)/MAX9698 (dual) are very fast TTL comparators manufactured with a high-frequency bipolar process (f_T = 6GHz) that are capable of very 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.
