PI6ULS5V9306: Dual Bi-Directional I2C-bus and SMBus Voltage-Level Translator (Universal Level Shifter / Voltage Translation (ULS))

Description

The PI6ULS5V9306 is a dual bidirectional I²C-bus and SMBus voltage-level translator with an enable (EN) input. It is operational from 0.9V to 3.3V (VREF1) and 1.8V to 5V (VREF2).

The PI6ULS5V9306 allows bidirectional voltage translations between 1.0V and 5V without the use of a direction pin. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. When EN is HIGH, the translator switch is on, and the SCL1 and SDA I/O are connected to the SCL2 and SDA2 I/O respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off, and a high-impedance state exists between ports.
