PCA9306D,118

Translators, Level Shifters Overview

The PCA9306D,118 is a dual bidirectional I2C-bus and SMBus voltage-level translator in an SO8 package. 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 supports Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus protocols. Maximum propagation delay is less than 1.5 ns. Operating temperature range is -40 °C to +105 °C.

Translators, Level Shifters Feature Summary

• Bidirectional translation between low-voltage (1.0 V to 3.6 V) and high-voltage (1.8 V to 5.5 V) domains without direction control pins
• Low ON-state resistance of 3.5 Ω minimizes signal distortion for SDA and SCL lines
• High-impedance state isolation when the enable input is LOW

Translators, Level Shifters Applications

• Mixed-mode I2C-bus applications requiring SDA and SCL line translation
• SMBus compatible system interconnects
• Connecting controllers operating at different bus frequencies (e.g., 100 kHz and 400 kHz)

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the Reel 13” Q1/T1 packing method as documented in the NXP datasheet. Confirm that the component matches the SO8 plastic small outline package specifications. Ensure compatibility with the specified ambient temperature operating range of -40 °C to +105 °C for your application environment.

Translators, Level Shifters Selection Notes

Select this component for designs requiring seamless voltage translation between mixed-mode I2C devices. Ensure pull-up resistors are sized according to driver sink current capabilities and node capacitance to maintain signal integrity. Verify that the enable pin logic levels satisfy the requirement where Vbias(ref)(2) is at least 1 V higher than Vref(1).

Translators, Level Shifters Part Context

This part belongs to the PCA9306 family of dual bidirectional translators. Other variants include DC1 (VSSOP8), DP (TSSOP8), JK (X2SON8), and GM (XQFN8). All share identical electrical characteristics but differ in physical package dimensions and footprint requirements.

Translators, Level Shifters Replacement Considerations

The Texas Instruments PCA9306DCU shares the same footprint and pinout as the PCA9306DC1. The PCA9306DC1/DG is functionally equivalent to the PCA9306DC1.
