MAX9685 - Ultra-Fast ECL-Output Comparator with Latch Enable

General Description

The MAX9685 is an ultra-fast ECL comparator manufactured with a high-frequency bipolar process (fT = 6GHz) capable of very short propagation delays.

This design maintains the excellent DC matching characteristics normally found only in slower comparators.

19-2398; Rev 1; 7/93 Ultra-Fast ECL-Output Comparator with Latch Enable _______________General Description The MAX9685 is an ultra-fast ECL comparator manufactured with a high-frequency bipolar process (fT = 6GHz) capable of very short propagation delays. This design maintains the excellent DC matching characteristics normally found only in slower comparators. The device is pin-compatible with the AD9685 and Am6685, but exceeds their AC characteristics. The MAX9685 has differential inputs and complementary outputs that are fully compatible with ECL-logic levels. 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.
