MAX690
_______________Ge n e ra l De s c rip t io n
The MAX9690 is an ultra-fast ECL comparator manufac-
____________________________Fe a t u re s
♦ 1.3ns Propagation Delay
tured with a high-frequency bipolar process (f = 6GHz)
T
capable of very short propagation delays. This design
maintains the excellent DC matching characteristics nor-
mally found only in slower comparators. The MAX9690 is
similar in function to the MAX9685, except the latch-
enable input is eliminated.
♦ +5V, -5.2V Power Supplies
♦ Pin-Compatible with CMP-08
♦ Available in Commercial, Extended-Industrial,
and Military Temperature Ranges
The MAX9690 is pin-compatible with the CMP-08 but
exceeds the AC characteristics of that device.
♦ Available in Small-Outline Package
The MAX9690 has differential inputs and complemen-
tary outputs that are fully compatible with ECL-logic lev-
els. 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.
