General Description
The ADuM1255 offers two open-drain channels, one
unidirectional and one bidirectional for applications,
such as I2C, that require data to be transmitted in both
directions on the same line, but have a unidirectional
clock. To prevent latch-up action, side 1 outputs
comprise special buffers that regulate the logic-low
voltage at 0.64V, and the input logic-low threshold is at
least 50mV lower than the output logic-low voltage. Side
2 features conventional buffers that do not regulate
logic-low output voltage.
The ADuM1255 features independent 2.25V to 5.5V
supplies on both side 1 and side 2 of the isolator. The
device operates up to 2MHz.
The ADuM1255 provides a disturbance-free bus
connection for hot-plug connections on side 2 by first
precharging the bus pins and then monitoring the bus
state for either an idle bus or detection of an I2C stop
condition before connecting side 1 and side 2.
The ADuM1255 is available in an 8-pin narrow-body
SOIC package. The devices are rated for operation at
ambient temperatures of -40°C to +125°C.
