Differential 5:1 or 4:1 ECL/PECL Multiplexers  
with Single/Dual Output Buffers  
General Description  
Features  
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

pulldowns to V ensure a low-default condition if the

select inputs are left open.  
Ordering Information  
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  
BB  
and clamping circuits that ensure low-default output  
states when the inputs are left open.
