NXS0104GU12X

Specialty Logic Overview

The NXS0104GU12X is a 4-bit dual supply translating transceiver with auto direction sensing, housed in an XQFN12 package (SOT1174-1). It supports bidirectional voltage level translation between VCC(A) ranging from 1.65 V to 3.6 V and VCC(B) ranging from 2.3 V to 5.5 V. The device features open-drain outputs, IOFF circuitry for partial power-down applications, and ESD protection exceeding 8000 V contact discharge on the B port. It operates within an ambient temperature range of -40 °C to +125 °C.

Specialty Logic Feature Summary

• Auto direction sensing enables bidirectional data flow without explicit control signals
• IOFF circuitry prevents damaging backflow current during partial power-down states
• Integrated internal pull-up resistors provide DC current sourcing capability
• Open-drain output architecture suitable for I2C and 1-wire interface applications

Specialty Logic Applications

• Desktop PC systems
• Handset devices
• Smartphone platforms
• Tablet computers

Specialty Logic Procurement Notes

Verify that the ordering suffix 'X' corresponds to the specific reel or cut tape packaging configuration required for your assembly line. Confirm the SOT1174-1 XQFN12 package dimensions match your PCB footprint design. Ensure the selected variant meets the -40 °C to +125 °C operating temperature requirements for your target environment.

Specialty Logic Selection Notes

Select this component when interfacing systems with distinct supply voltages where VCC(A) must not exceed VCC(B). The open-drain output type is optimal for bus architectures like I2C. Consider the XQFN12 package size constraints against available board space. Verify that the external driver impedance remains below 50 Ω to maintain specified data rates and transition times.

Specialty Logic Part Context

The NXS0104GU12X belongs to the NXS0104 family of dual supply translating transceivers manufactured by Nexperia. This family includes variants with different package options such as TSSOP14, DHVQFN14, and WLCSP12. All variants share identical electrical characteristics and functional descriptions, differing only in physical form factor and pinout arrangement.

Specialty Logic FAQ

How does the device handle power-down conditions?

The NXS0104GU12X includes IOFF circuitry that disables all output ports when either VCC(A) or VCC(B) is at ground potential, preventing damaging backflow current through the device.

Is special power-up sequencing required?

No special power-up sequencing is required. While VCC(A) must be less than or equal to VCC(B) during operation, the device can withstand VCC(A) being higher than VCC(B) during the power-up ramp phase without damage.
