GENERAL DESCRIPTION
The ADuM1250 / ADuM1251 1 are hot swappable digital isolators
with nonlatching, bidirectional communication channels that
are compatible with I 2 C interfaces. This eliminates the need for
splitting I 2 C signals into separate transmit and receive signals
for use with standalone optocouplers.
The ADuM1250 provides two bidirectional channels, supporting
a complete isolated I 2 C interface. The ADuM1251 provides one
bidirectional channel and one unidirectional channel for applica-
tions where a bidirectional clock is not required.
Figure 2. ADuM1251
Both the ADuM1250 and the ADuM1251 contain hot swap
circuitry to prevent glitching data when an unpowered card
is inserted onto an active bus.
These isolators are based on the i Coupler? chip scale transformer
technology from Analog Devices, Inc. i Coupler is a magnetic
isolation technology with functional, performance, size, and
power consumption advantages as compared to optocouplers.
With the ADuM1250 / ADuM1251 , i Coupler channels can be
integrated with semiconductor circuitry, which enables a complete
isolated I 2 C interface to be implemented in a small form factor.
