PCA9306GM,125

Translators, Level Shifters Overview

The PCA9306GM,125 is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by NXP Semiconductors. It operates with Vref(1) from 1.0 V to 3.6 V and Vbias(ref)(2) from 1.8 V to 5.5 V. The device provides bidirectional translation between 1.0 V and 5 V without a direction pin. It features an enable (EN) input, low ON-state resistance of 3.5 Ω typ, and propagation delay under 1.5 ns. Operating temperature ranges from -40 °C to +105 °C. It uses an XQFN-8 package.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation for SDA and SCL lines in mixed-mode I2C applications
• Compatible with Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus and SMBus devices
• Low ON-state resistance minimizes signal distortion and propagation delay
• Provides high-impedance isolation when the enable input is LOW

Translators, Level Shifters Applications

• Mixed-mode I2C bus systems requiring level shifting
• SMBus interface connections
• Systems running buses at different operating frequencies

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix ',125' corresponds to the XQFN8 package and reel packing method. Confirm that the component meets RoHS compliance requirements as specified in the product data sheet. Ensure the supply voltage conditions align with the operational limits defined in the datasheet before procurement.

Translators, Level Shifters Selection Notes

Select this component for applications requiring seamless bidirectional translation between low-voltage processors and higher-voltage peripherals. It is suitable for designs needing minimal propagation delay and open-drain I/O ports. Consider the XQFN8 package dimensions for PCB layout constraints.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 family of dual bidirectional translators. Other variants include SO8, TSSOP8, VSSOP8, XSON8, and X2SON8 packages. The GM suffix specifically denotes the XQFN8 plastic extremely thin quad flat package version.
