MAX9691/MAX9692/MAX9693 19-1789 Rev 2 1/12 Single/Dual, Ultra-Fast, ECL-Output Comparators with Latch Enable General Description Features The MAX9691/MAX9692/MAX9693 are ultra-fast ECL 1.2ns Propagation Delay comparators capable of very short propagation delays. 100ps Propagation Delay Skew Their design maintains the excellent DC matching char- 150ps Dispersion acteristics normally found only in slower comparators. 0.5ns Latch Setup Time The MAX9691/MAX9692/MAX9693 have differential inputs and complementary outputs that are fully com- 0.5ns Latch-Enable Pulse Width patible with ECL-logic levels. Output current levels are Available in MAX and QSOP Packages capable of driving 50 terminated transmission lines. The ultra-fast operation makes signal processing possi- +5V, -5.2V Power Supplies ble at frequencies in excess of 600MHz. Ordering Information The MAX9692/MAX9693 feature a latch-enable (LE) function that allows the comparator to be used in a TEMP PART PIN-PACKAGE sample-hold mode. When LE is ECL high, the compara- RANGE tor functions normally. When LE is driven ECL low, the MAX9691EUA -40C to +85C 8 MAX outputs are forced to an unambiguous ECL-logic state, MAX9691ESA -40C to +85C 8 SO dependent on the input conditions at the time of the latch input transition. If the latch-enable function is not MAX9691EPA -40C to +85C 8 PDIP used on either of the two comparators, the appropriate Note: Devices are also available in lead(Pb)-free/RoHS-compli- LE input must be connected to ground the companion ant packages. Specify lead-free by adding a + after the part number. LE input must be connected to a high ECL logic level. Ordering Information continued at the end of data sheet. These devices are available in SO, QSOP, and tiny MAX packages for added space savings.
