FEATURES

PIN ASSIGNMENT

6-PIN TSOC PACKAGE

§ Low impedance coupler to create large

common-ground, multi-level MicroLAN

networks

§ Keeps inactive branches pulled high to 5V

§ Simplifies network topology analysis by

logically decoupling devices on active

network segments

3.7 X 4.0 X 1.5 mm

§ Conditional search for fast event signaling

§ Auxiliary 1-Wire^TMline to connect a memory

chip or to be used as digital input

§ Programmable, general purpose open drain

control output

§ Communicates at 16.3k bits per second

§ Unique, factory-lasered and tested 64-bit

registration number (8-bit family code + 48-

bit serial number + 8-bit CRC tester) assures

absolute traceability because no two parts are

alike

§ 8-bit family code specifies device

communication requirements to bus master

§ Built-in multidrop controller ensures

compatibility with other MicroLAN products

§ Operating temperature range from -40°C to

+85°C

6-pin TSOC package

§ Compact, low cost 6-pin TSOC surface mount

package

DESCRIPTION

The MicroLAN coupler is an essential component to build and control 1-Wire MicroLAN networks with

multi-level branching. In contrast to approaches that switch the ground line, the coupler maintains a

common ground level for the whole network and keeps the inactive segments powered. This simplifies

supplying central or local power for additional circuitry and prevents loss of status of parasitically

powered devices. It also avoids disrupting communication caused by the parasitic power supply of 1-Wire

devices after activating a branch. The coupler does not contain any user-programmable memory. To label

a branch one can connect any 1-Wire memory device to the auxiliary 1-Wire output of the coupler. Both

the main and the auxiliary 1-Wire output are supported by a “smart-on” command. This command

generates a reset/presence sequence on the selected output before the electronic switch closes the contact

to the 1-Wire bus. This way the bus master can apply a ROM function command (optionally followed by

a memory function) to the devices on the just activated segment with all other devices in the network
