NTB0102JKZ

Translators, Level Shifters Overview

The NTB0102JKZ is a dual-supply translating transceiver with auto direction sensing, enabling bidirectional voltage level translation. 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 data rates up to 100 Mbps and includes IOFF circuitry for partial power-down applications. It is specified for ambient temperatures from -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for an extra control signal to manage data flow direction.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current.
• Inputs accept voltages up to 5.5 V, providing compatibility across different low-voltage nodes.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices operating at different supply voltages
• Microcontrollers (MCUs) requiring flexible voltage node translation
• Systems utilizing low voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V

Translators, Level Shifters Procurement Notes

Verify the specific package type matches the design requirements, as the NTB0102 family offers multiple options including TSSOP8, XSON8, and X2SON8. Confirm that the ordering suffix JKZ corresponds to the desired X2SON8 variant. Ensure the application environment stays within the specified temperature range of -40 °C to +125 °C. Check for any RoHS compliance documentation if required by the manufacturing process.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between distinct voltage domains is required without external direction control signals. The wide supply voltage ranges allow flexibility in system design. Consider the X2SON8 package for space-constrained designs. Ensure the driving source meets the minimum drive capability requirement for correct operation.

Translators, Level Shifters FAQ

How does the device handle partial power-down?

The IOFF circuitry disables the outputs when either VCC(A) or VCC(B) is switched off, preventing damaging backflow current through the device.

Is an external direction control signal required?

No, the device features auto direction sensing and does not require an extra input signal to control the direction of data flow.
