PI6ULS5V9306WEX

Translators, Level Shifters Overview

The PI6ULS5V9306WEX is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by Diodes Incorporated. It facilitates signal translation between low-voltage (VREF1: 0.9V to 3.3V) and high-voltage (VREF2: 1.8V to 5V) domains. The device operates within an ambient temperature range of -40°C to +85°C and supports a maximum pass switch current of 64 mA. Propagation delays are typically under 1.4 ns depending on the load capacitance and direction. It is housed in an SOIC-8 package.
