ADuM1253
ADuM1253 is I2C Isolator manufactured by Analog Devices.
Ultra-Low-Power, I2C Isolator with Unidirectional SCL, Extended VDD, Idle-Bus Hot-Swap, and Low VOL
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 prise 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...
