ADUM1254規(guī)格書詳情
General Description
The ADuM1254 offers two bidirectional, open-drain
channels for applications, such as I2C, that require data
to be transmitted in both directions on the same line. 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 ADuM1254 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 ADuM1254 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 a I2C stop
condition before connecting side 1 and side 2.
The ADuM1254 is available in an 8-pin narrow-body
SOIC package. The device is rated for operation at
ambient temperatures of -40°C to +125°C.
