Single/Dual, Very Fast TTL Latched Output Comparators

The MAX9686 (Single) and MAX9698 (Dual) are very fast, latched TTL comparators manufactured with a high-frequency bipolar process (fT = 6GHz). They are capable of very short propagation delays, yet maintain the excellent DC characteristics normally 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. 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 at the time of the latch transition. The outputs remain latched as long as the LE pin remains high. If latch-enable is not used, LE is tied to ground.
