NTB0101GM,115

Translators, Level Shifters Overview

The NTB0101GM,115 is a 1-bit dual supply translating transceiver with auto direction sensing and 3-state outputs. It enables bidirectional voltage level translation between VCC(A) (1.2 V to 3.6 V) and VCC(B) (1.65 V to 5.5 V). The device features IOFF circuitry for partial power-down mode operation, preventing damaging backflow current. Inputs accept voltages up to 5.5 V. It operates within an ambient temperature range of -40 °C to +125 °C and is housed in an XSON6 package (SOT886).

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for extra control signals to manage data flow direction.
• IOFF circuitry supports partial power-down applications by disabling outputs when supplies are off.
• High ESD protection capabilities exceeding specified JESD standards for both HBM and CDM events.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices operating at different supply voltages
• Microcontrollers (MCUs) requiring bidirectional data transfer between low voltage nodes
• Systems connecting 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains

Translators, Level Shifters Procurement Notes

Verify component status as the NTB0101 series has been discontinued with specific Last Time Buy and Last Time Ship dates defined by NXP. Confirm that the XSON6 package variant matches the required footprint for existing designs. Ensure compliance with RoHS directives and check for any relevant REACH SVHC declarations prior to final procurement decisions.

Translators, Level Shifters Selection Notes

Select this component for designs requiring a single-channel bidirectional translator with automatic direction detection. It is suitable for interfacing between varying low-voltage nodes without external direction control pins. Note that it is not recommended for open-drain applications like I2C or 1-Wire due to weak static drive strength; consider the NTS0101 for those specific use cases.

Translators, Level Shifters Part Context

The NTB0101 belongs to NXP's family of dual supply translating transceivers designed for robust voltage level shifting. This specific GM variant utilizes the SOT886 (XSON6) package, offering a compact solution for space-constrained PCB layouts. It shares functional similarities with other NTB series parts but differs in channel count and package dimensions.

Translators, Level Shifters FAQ

Can VCC(A) be powered higher than VCC(B) during normal operation?

No, during operation VCC(A) must never be higher than VCC(B). However, during power-up, either supply can be ramped up first without damaging the device.

Is the NTB0101 suitable for I2C-bus applications?

It is not recommended for open-drain driver applications such as I2C-bus or 1-Wire due to its low static drive strength. The NTS0101 is recommended for these applications instead.
