NTB0101AGWH

Translators, Level Shifters Overview

The NTB0101AGWH is a 1-bit dual supply translating transceiver with auto direction sensing, enabling bidirectional voltage level translation. It features two 1-bit I/O ports (A and B), 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 partial power-down via IOFF circuitry to prevent backflow current. It provides high ESD protection exceeding 2500 V HBM for port A and 15000 V HBM for port B. Latch-up performance exceeds 100 mA per JESD 78B Class II. Operating temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for extra control signals to manage data flow direction between ports.
• Dual supply architecture allows flexible translation between various low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V.
• IOFF circuitry enables partial power-down mode operation by disabling outputs to prevent damaging backflow currents when powered down.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices operating at different supply voltages
• Systems requiring bidirectional data transfer between low voltage logic domains

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix AGWH corresponds to the SC-88 plastic surface-mounted package (SOT363) with six leads. Confirm that the marking code tL matches the physical device identification. Ensure the procurement documentation references the correct product data sheet revision for the NTB0101A family to guarantee compatibility with design specifications.

Translators, Level Shifters Selection Notes

Select this component for applications requiring automatic direction sensing without external control logic. Ensure VCC(A) does not exceed VCC(B) during normal operation, although power-up sequencing flexibility exists. Verify that pull-up or pull-down resistors on I/O lines are above 50 kΩ to avoid contention issues due to low static drive strength. This device is unsuitable for open-drain driver applications like 1-Wire or I2C-bus.

Translators, Level Shifters Part Context

The NTB0101AGWH belongs to the NTB0101A series of auto direction sensing dual supply translators manufactured by NXP Semiconductors. It is part of a broader portfolio of voltage level shifting solutions designed for mixed-voltage system integration. The device shares architectural similarities with other members of the NTB and NTS families but is distinct in its 1-bit configuration and specific supply voltage ranges.

Translators, Level Shifters FAQ

Can VCC(A) be higher than VCC(B) during power-up?

Yes, during power-up VCC(A) can be greater than or equal to VCC(B) without damaging the device. However, during normal operation, VCC(A) must never be higher than VCC(B).

Is the NTB0101AGWH suitable for I2C-bus applications?

No, it is not recommended for open-drain driver applications such as I2C-bus due to its low static drive strength. The NTS0101 level translator is recommended for these applications.
