Diodes Incorporated PI4MSD5V95xA I²C / SMBus Switches
Diodes Incorporated PI4MSD5V95xA I2C/SMBus Switches are translating bi-directional switches controlled via the I2C bus. An active LOW reset input allows the switches to recover the downstream buses stuck in a low state. These switches operate at power supply voltage of 1.65V to 5.5V. Diodes Incorporated PI4MSD5V95xA provide voltage level translation between 1.2V, 1.8V, 2.5V 3.3V and 5V buses. Applications include blade servers, rack servers, home appliances, set-top boxes, wireless access, broadband access, digital cameras, HDD, and multi-function printers.
