ADM208ARZ is an interface integrated circuit designed for low-power, logic-level signal transmission applications. It is a fan-out driver with multiple receiver inputs, with a built-in power supply of 5V regulated down to 3.3V. It provides for low-voltage and low-power signal transmission between high-voltage and low-voltage peripherals. ADM208ARZ can be used in a variety of applications such as signal line expansion, signal level conversion, and as an isolation buffer between different voltage networks.

The integrated circuit is organized into two identical sections, a driver and a receiver. The driver section consists of seven logic outputs and a power supply, while the receiver section consists of seven logic inputs. The two sections are interconnected to provide a four-line, full-duplex, point-to-point data transmission circuit, with a common ground runs in between the two halves, forming a complete bus.

ADM208ARZ is designed with a 1-Wire interface, which is a low-power, low-voltage single-wire serial communication protocol used for short-range data transmission. The 1-Wire protocol requires that the receiver is capable of receiving signals from the driver and that the driver is capable of driving signals to the receiver. ADM208ARZ is designed to provide for the transmission of 1-Wire compatible signals between the two sections. The signals transmitted through the 1-Wire interface have a low-voltage logic threshold of 2.2V, making the ADM208ARZ an ideal choice for logic-level signal transmission applications.

The ADM208ARZ also incorporates a pair of Schmitt triggers on each input line to ensure a valid logic-level signal is detected. The device also includes two separate bias networks, which provide the necessary power to the receiver and driver sections, respectively. In addition, the voltage on both the receiver and driver sections can be adjusted separately, allowing for further optimization and flexibility in the design of the application.

The ADM208ARZ is a highly optimized and cost effective solution for logic-level signal transmission applications. It provides for high speed, low power communication with 1-Wire compatible signals, as well as power supply adjustment and Schmitt trigger protection. Furthermore, it offers the flexibility of using two separate bias networks, which allow the voltage on both the receiver and driver sections to be adjusted independently. All of these features make the ADM208ARZ an ideal solution for low-power, logic-level signal transmission applications.
