NCA9306GXX

Translators, Level Shifters Overview

The NCA9306GXX is a 2-channel bidirectional multi-voltage level translator in an X2SON8 package (SOT1233-2). It supports voltage translation between 0.95 V and 5.0 V without requiring a direction pin. The device features open-drain I/O ports with push-pull capability, supporting up to 100 MHz up translation and over 100 MHz down translation at ≤ 30 pF capacitive load. It operates within a temperature range of -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation for SDA and SCL lines without direction pins
• Supports mixed-mode signal operation with 5 V tolerant I/O pins
• Low ON-state resistance minimizes propagation delay and signal distortion
• High-impedance state available when the enable input is LOW

Translators, Level Shifters Applications

• GPIO, MDIO, PMBus, SMBus, SDIO, UART, and I²C interfaces in telecom infrastructure
• Industrial automation systems
• Personal computing devices
• Routers and industrial control equipment

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix 'GX' corresponds to the X2SON8 package (SOT1233-2) as specified in the manufacturer's documentation. Confirm the specific marking code 'h9' matches the physical component received. Ensure the application environment remains within the recommended operating conditions of -40 °C to +125 °C ambient temperature.

Translators, Level Shifters Selection Notes

Select this component for applications requiring flexible voltage translation between different logic levels without complex control logic. The absence of a direction pin simplifies system design. Verify that the required data rates do not exceed the specified limits under the target capacitive load conditions. Ensure pull-up resistors are provided on both sides of the translator for proper logic HIGH levels.

Translators, Level Shifters Part Context

The NCA9306 belongs to Nexperia's NCA series of logic ICs designed for I²C and SMBus bus systems. This specific variant utilizes the X2SON8 package, which offers a thermal-enhanced extremely thin small outline form factor. It is part of a family including TSSOP8, VSSOP8, and standard XSON8 packages, all sharing identical electrical characteristics but differing in physical dimensions.
