General Description

The MAX9384 fully differential dual 2:1 multiplexer

(mux) features extremely low propagation delay (560ps

max) and output-to-output skew (40ps max). The

device is ideal for clock and data multiplexing applica-

tions. The two 2:1 muxes are controlled individually or

simultaneously through mux select inputs COM_SEL,

SEL0, and SEL1. The mux select inputs are compatible

with ECL/PECL logic, and are referenced to on-chip

The differential inputs D, D can be configured to accept

a single-ended signal when the unused complementary

a reference voltage. All the differential inputs have bias

and clamp circuits that force the outputs to a low

providing low default inputs when the select inputs are

left open.

ECL, and is pin compatible with the MC100LVEL56 and

MC100EL56. The MAX9384 is offered in a 20-pin wide

SO package, and is specified for operation from -40

°C

to +85

°C.
