1-Wire Interface Adapters

Also known as 1-Wire Bus Masters, 1-Wire Interface Adapters are available in a wide variety of form factors and interface types. They are divided into two basic categories:

Intelligent 1-Wire Interface Adapters - relieve the host from the burden of generating the time-critical 1-Wire communication waveforms while supporting all Maxim 1-Wire and iButton devices with simple ASCII commands. This enables 1-Wire networks to be used by nearly any device which can read/write ASCII data via any of the following interfaces:
1-Wire Level Converters - require the host to generate the 1-Wire timing, and are compatible with Maxim Integrated's 1-Wire® Drivers.
