NTS0101GW,125

Translators, Level Shifters Overview

The NTS0101GW,125 is a dual-supply translating transceiver with auto direction sensing, designed for bidirectional voltage level translation. It features two 1-bit input-output ports (A and B), one output enable input (OE), and two supply pins (VCCA and VCCB). VCCA operates between 1.65 V and 3.6 V, while VCCB operates between 2.3 V and 5.5 V. The device supports maximum data rates of 50 Mbps in push-pull mode. It includes IOFF circuitry for partial power-down applications to prevent backflow current. The component is specified for operating temperatures from -40°C to +125°C and is housed in a 6-lead SC-88 plastic surface-mounted package (SOT363).

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without external control signals.
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent damaging backflow current.
• Inputs accept voltages up to 5.5 V, offering flexibility for interfacing different voltage nodes.
• High ESD protection performance exceeding standard requirements for both Human Body Model and Charged Device Model.

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO level shifting

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type, as the NTS0101 family includes multiple options such as XSON6 variants. Confirm the temperature range specification aligns with system requirements, noting that the GW suffix corresponds to the industrial grade range. Ensure compatibility with existing PCB footprints for the SC-88 package before finalizing procurement decisions.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional translation between low-voltage logic (1.65 V to 3.6 V) and higher-voltage nodes (up to 5.5 V). It is particularly suitable for open-drain applications like I2C or SMBus due to its internal pull-up resistors. Consider the auto-direction sensing feature to simplify design by eliminating the need for separate direction control pins compared to unidirectional translators.

Translators, Level Shifters Part Context

The NTS0101 belongs to NXP's portfolio of voltage level translators, specifically designed for dual-supply applications. It serves as a bridge between devices operating at different logic levels, facilitating communication in mixed-voltage environments. The device complements other NXP interface solutions by providing a compact, low-power option for signal integrity in space-constrained designs.

Translators, Level Shifters Replacement Considerations

Direct substitutes include the NTB0101 series, which offers similar functionality but may differ in output drive characteristics. Verify pinout compatibility and electrical specifications against alternative single-channel translators from other manufacturers if sourcing constraints require it.

Translators, Level Shifters FAQ

How does the NTS0101 handle partial power-down scenarios?

The device incorporates IOFF circuitry that automatically disables the outputs when either VCCA or VCCB is at ground potential. This prevents damaging backflow current through the device during power-down states.

What is the role of the OE pin on the NTS0101?

The Output Enable (OE) pin controls the state of the I/O ports. Setting OE to a LOW level forces all outputs into a high-impedance OFF-state, effectively disabling the translator regardless of the input signals.
