Overview
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 termination value of a line, depending on the state of a digital control line, allowing the connection to a coaxial cable or a twisted pair wire.
These devices are switchable 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 values 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 available in a tiny 5-pin SOT23 package.
All specifications are guaranteed over the extended temperature range of -40°C to +85°C.
