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.


Description

The MAX9389 is a fully differential, high-speed, low-jitter, 8-to-1 ECL/PECL multiplexer (mux) with dual output buffers. The device is designed for clock and data distribution applications, and features extremely low propagation
delay (310ps typ) and output-to-output skew (30ps max).

Three single-ended select inputs, SEL0, SEL1, and SEL2, control the mux function. The mux select inputs of MAX9389 are compatible with ECL/PECL logic, and are internally referenced to the on-chip reference output (VBB1, VBB2), nominally VCC - 1.425V. The select inputs accept signals between VCC and VEE. Internal pulldowns to VEE ensure
a low default condition if the select inputs are left open.

The differential inputs D_, D_ of MAX9389 can be configured to accept a single-ended signal when the unused complementary
input is connected to the on-chip reference output (VBB1, VBB2). All the differential inputs of MAX9389 have internal bias and clamping circuits that ensure a low output state when the inputs are left open.

The MAX9389 operates with a wide supply range VCC - VEE of 2.375V to 5.5V. The device is offered in 32-pin TQFP and thin QFN packages, and operates over the -40 to +85 extended temperature range.
