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.

FEATURES

● 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

● Conditional search for fast event signaling

● Auxiliary 1-WireTM line 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

● Compact, low cost 6-pin TSOC surface mount package
