PCA9306DP1,125

Translators, Level Shifters Overview

The PCA9306DP1,125 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 translation between 1.0 V and 5 V without direction pins. It features an enable (EN) input, low ON-state resistance of 3.5 Ω, and maximum propagation delay under 1.5 ns. It supports Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus protocols. The component is housed in a TSSOP8 package.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation for SDA and SCL lines without requiring direction control pins
• Low ON-state resistance minimizes signal distortion and propagation delay
• High-impedance isolation between ports when the enable input is LOW
• ESD protection exceeding 2000 V HBM and 1000 V CDM

Translators, Level Shifters Applications

• Mixed-mode I2C-bus applications connecting devices with different supply voltages
• SMBus interface level shifting
• Connecting I2C controllers to peripherals operating at distinct logic levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DP1,125 corresponds to the TSSOP8 package with 0.5 mm lead length and reel packing method. Confirm that the part number matches the manufacturer's current production status and datasheet revision. Ensure compatibility with required temperature ranges and packaging specifications before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component for designs requiring seamless bidirectional translation between low-voltage processors and higher-voltage I2C peripherals. The absence of direction pins simplifies circuit design compared to active switching solutions. Ensure pull-up resistors are sized appropriately for the target bus frequency and driver sink currents to maintain signal integrity.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 family of dual bidirectional translators. It shares functional characteristics with variants like PCA9306D and PCA9306DC1 but differs in physical package dimensions and manufacturing specifications. The DP1 suffix specifically denotes the TSSOP8 package variant with defined lead lengths.

Translators, Level Shifters Replacement Considerations

The Texas Instruments PCA9306DCU and PCA9306DCT share the same footprint and pinout as NXP variants. Verify electrical parameter equivalence and package mechanical dimensions before substituting.
