General Description

The MAX9386/MAX9387/MAX9388 are fully differential,

high-speed, low-jitter ECL/PECL multiplexers (muxes)

with output buffer(s). The devices are designed for

clock-and-data distribution applications, and feature

extremely low propagation delays (318ps, typ) and out-

put-to-output skews (3.9ps, typ). The MAX9386 is a 5:1

mux with a single output buffer. The MAX9387 is a 5:1

mux with dual output buffers, and is intended for use in

redundant systems. The MAX9388 is a 4:1 mux with a

single output buffer, and is pin compatible with the

MC100EP57.

Three single-ended select inputs, SEL0, SEL1, and

SEL2, control the mux function on the MAX9386/

MAX9387. The MAX9388 has two select inputs, SEL0

and SEL1. The mux select inputs are compatible with

ECL/PECL logic, and are internally referenced to the

select inputs are left open.

The differential inputs D_, D_ can be configured to

accept a single-ended signal when the unused comple-

mentary input is connected to the on-chip reference

and clamping circuits that ensure low-default output

states when the inputs are left open.

The MAX9386/MAX9387/MAX9388 operate with a wide

supply range

MAX9386/MAX9388 are offered in 20-pin TSSOP and

QSOP packages. The MAX9387 is offered in 24-pin

TSSOP and QSOP packages.
