NTS0104UK,012

Translators, Level Shifters Overview

The NTS0104UK,012 is a 4-bit dual-supply translating transceiver in a WLCSP12 package. It supports VCC(A) from 1.65 V to 3.6 V and VCC(B) from 2.3 V to 5.5 V. The device features auto direction sensing for bidirectional translation between voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V. It includes IOFF circuitry for partial power-down applications, preventing backflow current. The component operates within temperature ranges of -40 °C to +85 °C and -40 °C to +125 °C.

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 currents.
• Inputs accept voltages up to 5.5 V, facilitating interface with higher voltage systems.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix UK corresponds to the WLCSP12 package variant when sourcing. Confirm that the supplier documentation explicitly references the NTS0104UK part number to ensure correct pinout and marking code (s04). Cross-reference the manufacturer's latest datasheet revision to validate electrical characteristics and package dimensions against your design requirements.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with different supply voltages requiring bidirectional data flow. Ensure VCC(A) remains lower than or equal to VCC(B) during recommended operating conditions. Consider the WLCSP12 package constraints for PCB layout, specifically regarding the substrate pad connection. Verify that the application does not require push-pull driving on both sides simultaneously, as open-drain drivers are primarily targeted.

Translators, Level Shifters Part Context

This device belongs to the NTS0104 family of dual-supply translating transceivers. It shares functional similarities with other variants like NTS0104PW and NTS0104BQ but differs in packaging. The UK suffix denotes the Wafer Level Chip Scale Package (WLCSP12), which offers a compact form factor suitable for space-constrained designs compared to TSSOP or QFN options.

Translators, Level Shifters FAQ

How does the device handle power-down states?

The NTS0104UK includes IOFF circuitry that disables the output when either VCC(A) or VCC(B) is at GND level, preventing damaging backflow current through the device during partial power-down applications.

Is an external direction control signal required?

No, the device features auto direction sensing. It acts as a switch-type translator that automatically detects the direction of data flow between port A and port B without requiring an extra input signal.
