MAX9693ESE+

The MAX9693ESE+ is a dual, ultra fast, ECL output comparator with latch enable in 16 pin NSOIC package. The ultra fast ECL comparator is capable of very short propagation delays. Their design maintains the excellent DC matching characteristics normally found only in slower comparators. It has differential inputs and complementary outputs that are fully compatible with ECL logic levels. The ultra fast operation makes signal processing possible at frequencies in excess of 600MHz. It features a latch-enable (LE) function that allows the comparator to be used in a sample-hold mode. When LE is ECL high, the comparator functions normally. When LE is driven ECL low, the outputs are forced to an unambiguous ECL logic state, dependent on the input conditions at the time of the latch input transition. If the latch-enable function is not used on either of the two comparators, the appropriate LE input must be connected to ground, the companion LE input must be connected to a high ECL logic level.
