Single/Dual, Very Fast TTL Output Comparators MAX9686/MAX9698
General Description
The MAX9686 (single)/MAX9698 (dual) are very fast TTL comparators manufactured with a high-frequency bipolar process (fT = 6GHz) that are capable of very short propagation delays, yet maintain the excellent DC matching characteristics that are normally found only in slower comparators. The MAX9698 is a dual version of the MAX9686. The MAX9686/MAX9698 have differential inputs and complementary outputs that are fully compatible with TTL logic levels. The extremely short propagation delays allow signal processing at frequencies in excess of 200MHz. When the latch enable input goes high, the outputs go to the states defined by the input condition at the time of the latch transition. The outputs remain latched as long as the LE pin remains high. If the latch enable function is not used, the LE pin must be tied to ground. 6ns Propagation Delay 2ns Latch Setup Time +5V, -5.2V Power Supplies Pin Compatible to LT1016, Am686 Available in Commercial and Military Versions Available in SO

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Applications Information
Layout
Because of the large gain-bandwidth characteristic of the MAX9686 and MAX9698, special precautions need to be taken if the high-speed capabilities of the devices are to be realized. A PC board with ground plane should be considered mandatory. All decoupling capacitors should be mounted as close as possible to the power-supply pins. For low-impedance applications, microstrip layout at the input may be helpful. Close attention should be paid to the bandwidth of the decoupling and terminating components. Chip components to minimize lead inductance can be used as an
advantage. An unused latch enable pin must be connected to ground.
Input Slew-Rate Requirements
As with all high-speed comparators, the high gainbandwidth product of these devices creates oscillation problems when the input traverses through the linear region. For clean switching without oscillation or steps in the output waveform, the input must meet certain minimum slew-rate requirements. The tendency of the part to oscillate is a function of the layout and the source impedance of the circuit employed. Both poor layout and larger source impedance will increase the minimum slew-rate requirement.
