_______________General Desc ription
The MAX9687 is a dual, ultra-fast ECL comparator
manufactured with a high-frequency bipolar process
(f
T
= 6GHz) capable of very short propagation delays.
This design maintains the excellent DC matching char-
acteristics normally found only in slower comparators.
The MAX9687 is pin-compatible with the AD9687 and
Am6687, but exceeds their AC characteristics.
The MAX9687 has differential inputs and complemen-
tary outputs that are fully compatible with ECL-logic lev-
els. Output current levels are capable of driving 50
terminated transmission lines. The ultra-fast operation
makes signal processing possible at frequencies in
excess of 600MHz.
A latch-enable (LE) function is provided to allow the
comparator to be used in a sample/hold or track/hold
mode. The latch-enable inputs are designed to be dri-
ven from the complementary outputs of a standard ECL
functions normally. When LE is forced low and –—is
high, the comparator outputs are locked in the logical
states determined by the input conditions at the time of
the latch transition. If the latch-enable function is not
used on either of the two comparators, the appropriate
LE input must be connected to ground; the companion
