NTSX2102GU8H

Translators, Level Shifters Overview

The NTSX2102GU8H is a dual-supply translating transceiver with open-drain outputs and auto direction sensing, designed for 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)). Both supplies operate between 1.65 V and 5.5 V, supporting translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V nodes. The device includes IOFF circuitry for partial power-down applications to prevent backflow current.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional data flow without external control signals
• IOFF circuitry supports partial power-down mode by disabling outputs during power loss
• Open-drain architecture targets I2C or 1-wire buses using open-drain drivers

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO expansion

Translators, Level Shifters Procurement Notes

Verify the package type matches the design requirements, as the NTSX2102 series offers XQFN8 and XSON8 options. Confirm that the specific ordering suffix corresponds to the desired tape and reel quantity. Ensure the selected variant meets the required temperature range of -40 °C to +85 °C for the intended operating environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with different supply voltages requiring bidirectional translation. The open-drain output type is suitable for bus applications like I2C. Consider the maximum data rate capabilities relative to the supply voltage and load capacitance to ensure signal integrity within the specified propagation delay limits.

Translators, Level Shifters Part Context

This part belongs to the NTSX2102 family of dual-supply translating transceivers manufactured by NXP Semiconductors. The GU8H suffix indicates the XQFN8 package configuration supplied in a tape and reel format. It is an active component designed for low-voltage digital logic level shifting in embedded systems.

Translators, Level Shifters Replacement Considerations

The datasheet identifies NTSX0102TLH as a drop-in replacement for the discontinued NTSX2102GD. Note that the TL package has a center pad unlike the GD package; verify PCB layout compatibility regarding traces under the package area.
