PCA9306JKZ

Translators, Level Shifters Overview

The PCA9306JKZ 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 features an enable (EN) input, low ON-state resistance of 3.5 Ω typical, and propagation delay under 1.5 ns. It supports Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus devices. The component is housed in an X2SON-8 package.

Translators, Level Shifters Feature Summary

• Bidirectional translation between 1.0 V and 5 V without direction pins
• Low ON-state resistance for minimal signal distortion
• High-impedance state when disabled for bus isolation
• ESD protection exceeding 2000 V HBM

Translators, Level Shifters Applications

• Mixed-mode I2C-bus applications
• SMBus interface translation
• Connecting controllers operating at different frequencies

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix JKZ corresponds to the X2SON8 package type and standard marking configuration. Confirm that the required packing method aligns with Reel 7” Q1/T1 specifications. Ensure environmental compliance requirements match RoHS directives before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component for designs requiring seamless voltage translation between low-voltage processors and higher-voltage peripherals. Ensure pull-up resistors are sized according to driver sink current capabilities. Verify that the EN pin logic levels maintain at least a 1 V difference relative to Vref(1) for optimal operation.

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 PCA9306GM but differs in physical packaging. The X2SON8 form factor provides a compact solution for space-constrained printed-circuit board layouts.

Translators, Level Shifters Replacement Considerations

The PCA9306GF is functionally identical but utilizes the XSON8 package. Both parts share the same footprint and pinout compatibility within their respective package families.
