NTSX2102GU8X

Translators, Level Shifters Overview

The NTSX2102GU8X is a dual-supply translating transceiver with auto direction sensing, designed for bidirectional voltage level translation. It features two 2-bit input-output ports (An and Bn) and one output enable input (OE). Both supply pins, VCC(A) and VCC(B), operate within a range of 1.65 V to 5.5 V, supporting translation between standard voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device includes IOFF circuitry for partial power-down applications, preventing backflow current when powered down. It supports maximum data rates up to 50 Mbps and operates from -40 °C to +85 °C.

• UART connections
• GPIO expansion

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'X' against official documentation to confirm tape-and-reel packaging status, as datasheet tables list 'NTSX2102GU8' without the suffix. Confirm RoHS compliance and REACH SVHC declarations via the manufacturer's Certificate of Analysis. Ensure the package type matches the XQFN8 SOT1309-1 outline specifications.

Translators, Level Shifters Selection Notes

Select this component for designs requiring flexible voltage translation between 1.65 V and 5.5 V domains. The open-drain output structure necessitates external pull-up resistors on both A and B ports. Consider the 600 pF maximum capacitive load limit and ensure PCB trace lengths minimize reflections to avoid one-shot retriggering during high-speed transitions.

Translators, Level Shifters Part Context

The NTSX2102 series comprises dual-supply translating transceivers available in multiple packages including XQFN8, XSON8, and TSSOP8. The GU8 variant specifically denotes the XQFN8 package (SOT1309-1). This family targets point-to-point applications where devices operate at different supply voltages, offering a compact solution for system integration without complex control logic.

Translators, Level Shifters FAQ

How does the device handle partial power-down?

The integrated IOFF circuitry disables outputs when either VCC(A) or VCC(B) is at GND level, preventing damaging backflow current through the device.

What determines the maximum data rate?

The maximum data rate is dependent on the output impedance and edge-rate of the external open-drain driver, as well as the capacitive loading on the lines.
