NXB0104PWJ

Translators, Level Shifters Overview

The NXB0104PWJ is a dual supply translating transceiver with auto direction sensing and 3-state outputs, manufactured by Nexperia. It features two 4-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)). VCC(A) operates between 1.2 V and 3.6 V, while VCC(B) operates between 1.65 V and 5.5 V. The device supports bidirectional voltage level translation between low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Pins An and OE are referenced to VCC(A), and pins Bn are referenced to VCC(B). A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state. The device is fully specified for partial power-down applications using IOFF circuitry.

Translators, Level Shifters Feature Summary

• Dual supply translating transceiver with auto direction sensing
• IOFF circuitry provides partial Power-down mode operation
• Inputs accept voltages up to 5.5 V
• ESD protection: HBM class 2 exceeds 2500 V for A port; HBM class 3B exceeds 15000 V for B port

Translators, Level Shifters Applications

• Voltage level translation between different supply domains
• Partial power-down applications
• Bidirectional data transfer interfaces

Translators, Level Shifters Procurement Notes

Verify the specific package type TSSOP14 (SOT402-1) matches your PCB footprint requirements. Confirm that the operating conditions adhere to the recommended limits where VCC(A) must be less than or equal to VCC(B) during normal operation. Ensure pull-up or pull-down resistors on I/O lines are kept higher than 50 kΩ to avoid output contention issues. Check that the device is suitable for your application as it is not recommended for open drain driver applications such as 1-Wire or I2C.

Translators, Level Shifters Selection Notes

Select this component when interfacing devices operating at different supply voltages requiring bidirectional translation. It is suitable for systems needing auto direction sensing without extra control signals. Consider the wide supply voltage range and ESD protection levels for robust designs. Note that it is not ideal for open drain applications like I2C; consider the NXS0104 for those cases instead.

Translators, Level Shifters Part Context

The NXB0104 series includes multiple package options such as TSSOP14 (NXB0104PW), DHVQFN14 (NXB0104BQ), and XQFN12 (NXB0104GU12). All variants share the same functional characteristics but differ in physical dimensions and lead configurations. The PWJ suffix indicates the TSSOP14 package variant with specific ordering and marking codes.

Translators, Level Shifters Replacement Considerations

For open drain applications like I2C or 1-Wire, the NXS0104 is recommended instead of the NXB0104 due to its suitability for such driver types.
