Product details

Overview

NTS0104UK-Q100 from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in WLCSP12 package, supporting 1.65 V–3.6 V on side A and 2.3 V–5.5 V on side B, with 50 Mbps push-pull data rate and AEC-Q100 Grade 1 qualification for automotive I²C/SMBus interfaces.

For engineers reviewing the NTS0104UK-Q100 datasheet, NTS0104UK-Q100 pinout, NTS0104UK-Q100 application, or NTS0104UK-Q100 equivalent, key selection criteria include open-drain-compatible auto-direction sensing, IOFF-enabled partial power-down, ±1 µA OFF-state leakage, 1.2 mm × 1.6 mm wafer-level chip-scale footprint, and guaranteed operation from −40 °C to +125 °C.

Technical Context

The NTS0104UK-Q100 implements a switch-type architecture using an N-channel pass-gate transistor with gate bias set ~1 V_TH above the lower supply rail, enabling passive bidirectional translation without external direction control. Its output edge-rate accelerator (one-shot circuit) actively drives rising edges via internal PMOS transistors, reducing t_TLH to ≤9.5 ns at 3.3 V.

Each port integrates 10 kΩ internal pull-up resistors-A-side to V_CC(A), B-side to V_CC(B)-and supports independent supply sequencing: V_CC(A) may ramp before or after V_CC(B) without damage. IOFF circuitry disables outputs during power-down, limiting backflow current to ±1 µA.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC(A) Range	1.65 V to 3.6 V - enables interface between 1.8 V/2.5 V/3.3 V logic domains on A-side
V_CC(B) Range	2.3 V to 5.5 V - supports translation to 2.5 V/3.3 V/5.0 V systems on B-side
Data Rate	50 Mbps - sufficient for high-speed I²C Fast-mode Plus (1 Mbps) and UART up to 25 Mbps
Propagation Delay	≤7.3 ns (A→B, −40 °C to +125 °C, V_CC(A)=1.8 V, V_CC(B)=5.0 V) - ensures timing margin in automotive control loops
IOFF Leakage	±1 µA max - prevents damaging backflow when either supply is powered down
ESD Robustness	B-port: >15 kV HBM - protects against handling and system-level ESD in vehicle cabin modules
Operating Temp	−40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and ADAS applications

Pinout & Package

NTS0104UK-Q100 uses WLCSP12 (wafer-level chip-size package), 1.20 mm × 1.60 mm × 0.56 mm body, with 12 solder bumps and backside coating. No thermal pad required; substrate attached via conductive die attach.

A1–A4 (A3,B3,C3,D3)	Bi-directional I/O (A-side)	Open-drain compatible; internally pulled up to V_CC(A) with 10 kΩ; referenced to A-supply
GND (D2)	Ground reference	Common return for both supplies; required for ESD path and signal integrity
OE (C2)	Output enable (active HIGH)	Controls all I/Os; LOW forces high-impedance state; referenced to V_CC(A)
B1–B4 (D1,C1,B1,A1)	Bi-directional I/O (B-side)	Open-drain compatible; internally pulled up to V_CC(B) with 10 kΩ; referenced to B-supply
V_CC(B) (A2)	Supply B reference	Power domain for B1–B4; sets VOH/VOL levels and pull-up strength on B-side

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional voltage translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NTB0104-Q100	Push-pull optimized; lacks auto-direction sensing; requires external DIR control signal	Better suited for high-speed UART where direction is known and fixed	Select when deterministic direction control is available and higher drive strength (>50 mA) is needed
TXS0104E-Q1	TI part; same 4-bit auto-sensing function but different IOFF behavior and 1.65–5.5 V dual-rail range	Wider V_CC overlap allows single-rail 3.3 V operation; not AEC-Q100 qualified	Choose for non-automotive industrial designs requiring broader supply flexibility and TI ecosystem support

Compared with NTB0104-Q100 and TXS0104E-Q1, the NTS0104UK-Q100 uniquely combines AEC-Q100 Grade 1 qualification, WLCSP12 footprint, and true auto-direction sensing-making it the only option for space-constrained, safety-critical automotive I²C nodes requiring zero-direction-pin integration.

FAQ

What is the maximum capacitive load the NTS0104UK-Q100 can drive reliably?

The NTS0104UK-Q100's one-shot edge accelerator has a fixed pulse duration (~50 ns). To ensure the output reaches V_CCO/2 within this window, total lumped capacitance-including PCB trace, connector, and load-must remain below 30 pF. Exceeding this limit risks incomplete rising-edge acceleration and potential retriggering. Layout best practices include short traces (<2 cm), controlled impedance routing, and avoiding stubs.

Does the NTS0104UK-Q100 require external pull-up resistors for I²C operation?

No. The NTS0104UK-Q100 integrates 10 kΩ pull-up resistors on both A-side (to V_CC(A)) and B-side (to V_CC(B)) I/Os. These meet standard I²C Fast-mode (400 kHz) requirements when V_CC ≥ 2.5 V. For higher speeds (Fast-mode Plus) or stronger pull-ups, add external resistors in parallel-but note that lower values reduce VOL margin.

Can V_CC(A) and V_CC(B) be powered from different sources with independent sequencing?

Yes. The NTS0104UK-Q100 supports independent power-up sequencing: either supply may ramp first without damage. During power-down, IOFF circuitry automatically disables outputs when either V_CC(A) or V_CC(B) falls below operational threshold, preventing backflow current. This eliminates need for external power sequencers in multi-rail automotive ECUs.

How does the auto-direction sensing work in the NTS0104UK-Q100?

The NTS0104UK-Q100 uses a passive switch architecture with an N-channel pass-gate transistor whose gate bias is dynamically set ~1 V_TH above the lower supply rail. When one side pulls low, the pass-gate turns on, allowing current flow. The edge-rate accelerator detects input transitions crossing V_CCI/2 and briefly activates PMOS drivers to boost rising edges-no direction pin or control logic is involved.

Is the NTS0104UK-Q100 pin-compatible with other variants in the NTS0104-Q100 family?

No. While NTS0104PW-Q100 (TSSOP14) and NTS0104BQ-Q100 (DHVQFN14) share identical electrical functionality and logic, the NTS0104UK-Q100 uses WLCSP12 with distinct ball mapping (12 bumps vs 14 leads). Pin-to-pin compatibility does not exist across packages; redesign is required when migrating to or from the WLCSP variant.
