_______________General Description

The MAX9690 is an ultra-fast ECL comparator manufac-

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.

The MAX9690 is pin-compatible with the CMP-08 but

exceeds the AC characteristics of that device.

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 50

Ω

terminated transmission lines. The ultra-fast operation

makes signal processing possible at frequencies in

excess of 600MHz.
