Single/Dual, Ultra-Fast, ECL-Output Comparators with Latch Enable MAX9691/MAX9692/MAX9693 General Description Features
The MAX9691/MAX9692/MAX9693 are ultra-fast ECL o
1.2ns Propagation Delay
comparators capable of very short propagation delays. o
100ps Propagation Delay Skew
Their design maintains the excellent DC matching char- acteristics normally found only in slower comparators. o
