MAX9692EUB+T

P1-P3P4-P6P7-P9P10-P12
General Description
The MAX9691/MAX9692/MAX9693 are ultra-fast ECL
comparators capable of very short propagation delays.
Their design maintains the excellent DC matching char-
acteristics normally found only in slower comparators.
The MAX9691/MAX9692/MAX9693 have differential
inputs and complementary outputs that are fully com-
patible with ECL-logic levels. Output current levels are
capable of driving 50Ω terminated transmission lines.
The ultra-fast operation makes signal processing possi-
ble at frequencies in excess of 600MHz.
The MAX9692/MAX9693 feature a latch-enable (LE)
function that allows the comparator to be used in a
sample-hold mode. When LE is ECL high, the compara-
tor functions normally. When LE is driven ECL low, the
outputs are forced to an unambiguous ECL-logic state,
dependent on the input conditions at the time of the
latch input 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
LE input must be connected to a high ECL logic level.
These devices are available in SO, QSOP, and tiny
µMAX
®
packages for added space savings.

THE OUTPUTS ARE OPEN EMITTERS, REQUIRING EXTERNAL PULLDOWN
RESISTORS. THESE RESISTORS MAY BE IN THE RANGE OF 50Ω TO 200Ω
CONNECTED TO -2.0V, OR 240Ω TO 2000Ω CONNECTED TO -5.2V.
