MAX9387EUG+ Datasheet MAX9387EUG+, MAX9386EUP+ | P1-P3

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

on-chip output V

, nominally V

- 1.425V. The select

inputs accept signals between V

and V

. Internal

pulldowns to V

ensure a low-default condition if 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

output V

. All the differential inputs have internal bias

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

- V

EE|

of 2.375V to 5.5V. The

MAX9386/MAX9388 are offered in 20-pin TSSOP and

QSOP packages. The MAX9387 is offered in 24-pin

TSSOP and QSOP packages.

ABSOLUTE MAXIMUM RATINGS

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.
