MAX9687

_______________Ge n e ra l De s c rip t io n

The MAX9687 is a d ua l, ultra -fa s t ECL c omp a ra tor

manufactured with a high-frequency bipolar process

____________________________Fe a t u re s

♦ 1.4ns Propagation Delay

(f = 6GHz) capable of very short propagation delays.

♦ 0.5ns Latch Setup Time

This design maintains the excellent DC matching char-

acteristics normally found only in slower comparators.

♦ 2.0ns Latch-Enable Pulse Width

♦ +5V, -5.2V Power Supplies

The MAX9687 is pin-compatible with the AD9687 and

Am6687, but exceeds their AC characteristics.

♦ Pin-Compatible with AD9687, Am6687, SP9687

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 50Ω

terminated transmission lines. The ultra-fast operation

makes signal processing possible at frequencies in

excess of 600MHz.

♦ Available in Commercial, Extended-Industrial,

and Military Temperature Ranges

♦ Available in Narrow SO Package

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-
