Single/Dual, Ultra-Fast, ECL-Output Comparators with Latch Enable
General Description
The MAX9691/MAX9692/MAX9693 are ultra-fast ECL comparators capable of very short propagation delays. Their design maintains the excellent DC matching characteristics normally found only in slower comparators. The MAX9691/MAX9692/MAX9693 have differential inputs and complementary outputs that are fully compatible with ECL-logic levels. Output current levels are capable of driving 50Ω terminated transmission lines. The ultra-fast operation makes signal processing possible at frequencies in excess of 600MHz. The MAX9692/MAX9693 feature 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.
