NTS0102JKZ

Translators, Level Shifters Overview

The NTS0102JKZ is a 2-bit dual supply translating transceiver with auto direction sensing, packaged in X2SON8. It enables bidirectional voltage level translation between VCC(A) (1.65 V to 3.6 V) and VCC(B) (2.3 V to 5.5 V). The device supports push-pull data rates up to 50 Mbit/s and includes IOFF circuitry for partial power-down applications. It features ESD protection exceeding 2500 V HBM on the A port and 8000 V HBM on the B port, with latch-up performance exceeding 100 mA.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for an external control signal to manage data flow direction.
• IOFF circuitry prevents damaging backflow current when either supply rail is powered down.
• Integrated internal pull-up resistors provide DC current sourcing capability for open-drain drivers.

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO expansion

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix JKZ corresponds to the X2SON8 package variant. Confirm that the required temperature range of -40 °C to +125 °C aligns with the system specifications. Ensure the design accommodates the distinct pinout configuration associated with the SOT2015-1 package footprint.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems operating at different voltage nodes such as 1.8 V, 2.5 V, 3.3 V, or 5.0 V. The device is suitable for point-to-point applications requiring open-drain or push-pull driver compatibility. Verify that the maximum data rate requirements do not exceed the specified limits under the target load conditions.

Translators, Level Shifters Part Context

This part belongs to the NXP Semiconductors NTS0102 family of dual supply translating transceivers. The family offers multiple package options including TSSOP8, XSON8, and X2SON8 variants. All members share the same core functionality regarding bidirectional voltage translation and auto-direction sensing capabilities.

Translators, Level Shifters Replacement Considerations

The NTS0102TLH serves as a drop-in replacement for the discontinued NTS0102GD. When replacing GD packages with TL packages, verify PCB layout constraints regarding center pads to mitigate potential EMI risks if traces exist underneath.

Translators, Level Shifters FAQ

How does the device handle power-down states?

The NTS0102JKZ utilizes IOFF circuitry to disable outputs and prevent damaging backflow current when either VCC(A) or VCC(B) is switched off.

Is an external direction control signal required?

No, the device employs auto direction sensing to automatically determine the data flow direction without additional control inputs.
