General Description
The ADuM1253 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 ADuM1253 features independent 1.71V to 5.5V
supplies on both side 1 and side 2 of the isolator. The
device operates up to 2MHz. The ultra-low standby
current of 21μA per side is ideal for battery-operated
systems.
The ADuM1253 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 ADuM1253 is available in an 8-pin narrow SOIC
package. The device is rated for operation at ambient
temperatures of -40°C to +125°C.
