MAX3408 Overview

75з/100з/120з Switchable Termination Networks

19-2141; Rev 0; 8/01
75Ω/100Ω/120Ω Switchable Termination
Networks
General Description
The MAX3406/MAX3407/MAX3408 are general-purpose
line-terminating networks designed to change the termi-
nation value of a line, depending on the state of a digi-
tal control line, allowing the connection to a coaxial
cable or a twisted pair wire. These devices are switch-
able between 75Ω, 100Ω, and 120Ω. The MAX3406
can switch from 75Ω to 100Ω, the MAX3407 can switch
from 75Ω to 120Ω, and the MAX3408 can switch from
100Ω to 120Ω termination. Termination resistance val-
ues are guaranteed to ±2.5% through -40°C to +85°C
and for signal levels of ±3.6V.
The MAX3406/MAX3407/MAX3408 consume only 50µA
supply current and are fully specified for operation from
a +4.5V to +5.5V power supply. These devices are avail-
able in a tiny 5-pin SOT23 package. All specifications
are guaranteed over the extended temperature range of
-40°C to +85°C.
