NTS0104UK-Q100Z

Translators, Level Shifters Overview

The NTS0104UK-Q100 is a 4-bit dual-supply translating transceiver with auto direction sensing, enabling bidirectional voltage level translation. It features two 4-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)). VCC(A) operates between 1.65 V and 3.6 V, while VCC(B) operates between 2.3 V and 5.5 V. The device supports maximum data rates of 50 Mbps in push-pull configurations. It includes IOFF circuitry for partial power-down applications to prevent damaging backflow current.

Translators, Level Shifters Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard
• IOFF circuitry provides partial power-down mode operation preventing backflow current
• Inputs accept voltages up to 5.5 V regardless of the active supply rail
• High ESD protection exceeding specified thresholds for both A and B ports

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART communication links
• General Purpose Input/Output (GPIO) expansion

Translators, Level Shifters Procurement Notes

Verify the specific package variant against design requirements, as the UK suffix denotes a WLCSP12 wafer level chip-size package. Confirm that the ordering suffix matches the intended thermal and mechanical constraints for the target PCB layout. Ensure compatibility with the required temperature range specifications during procurement planning.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between low-voltage logic (1.8V-3.3V) and higher voltage nodes (up to 5.0V) is required. The auto-direction sensing eliminates the need for explicit direction control signals. Verify that the system can accommodate the internal pull-up resistors or plan for external parallel resistance if lower impedance is needed.

Translators, Level Shifters Part Context

This device belongs to the NTS0104-Q100 family of dual-supply translating transceivers designed for automotive and industrial environments. It serves as a bridge between systems operating at different supply voltages, facilitating asynchronous communication. The family includes variations in packaging such as TSSOP14 and DHVQFN14 to suit different board space and thermal management needs.

Translators, Level Shifters FAQ

Does the device require power supply sequencing?

No special power-up sequencing is required. Either power supply can be ramped up first without damaging the device.

How is the high-impedance state maintained during power transitions?

The OE pin should be tied to GND through a pull-down resistor to ensure the high-impedance OFF-state during power-up or power-down.
