NXB0102GTX

Translators, Level Shifters Overview

The NXB0102GTX is a dual supply translating transceiver with auto direction sensing and 3-state outputs, manufactured by Nexperia. It features two 2-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.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without requiring an extra control signal for data flow direction.
• IOFF circuitry provides partial power-down mode operation, disabling outputs to prevent damaging backflow current when powered down.
• High ESD protection capabilities exceed 2500 V for the A port (HBM Class 2), 15000 V for the B port (HBM Class 3B), and 1500 V (CDM Class C3).
• Latch-up performance exceeds 100 mA per JESD 78B Class II standards.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices or systems operating at different supply voltages.
• Partial power-down applications utilizing IOFF circuitry to manage power states safely.

Translators, Level Shifters Procurement Notes

Verify the specific package variant against your design requirements, as the NXB0102 series includes XSON8 (GT), VSSOP8 (DC), and WLCSP8 (UN) options. Confirm that the ordering suffix matches the desired physical footprint and lead configuration. Ensure compatibility with your PCB layout constraints regarding body width and terminal pitch before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces between logic families operating at distinct voltage levels such as 1.2 V, 1.8 V, 3.3 V, or 5.0 V. The auto-direction sensing feature simplifies board design by eliminating the need for explicit direction control signals. Consider the IOFF capability if your system requires safe handling during power-down sequences to prevent back-powering issues on inactive buses.

Translators, Level Shifters Part Context

The NXB0102 belongs to Nexperia's family of dual supply translating transceivers designed for robust bidirectional communication. Unlike unidirectional translators, it automatically detects signal flow direction between the A and B ports. The inclusion of an output enable pin allows for precise control over bus states, making it suitable for complex multi-master or shared bus architectures where contention must be managed effectively.

Translators, Level Shifters Replacement Considerations

For open-drain driver applications like I2C or 1-Wire, the NXS0102 is recommended instead due to its superior pull-up/pull-down resistor handling characteristics. Verify that any substitute maintains the required VCC(A) and VCC(B) voltage ranges and offers comparable ESD protection levels for your specific environmental conditions.
