Product details
Overview
NTB0104UK,012 from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level transceiver in WLCSP12 package, supporting 1.2 V to 3.6 V on side A and 1.65 V to 5.5 V on side B, with IOFF-enabled partial power-down for automotive infotainment and ADAS domain controllers.
For engineers reviewing the NTB0104UK,012 datasheet, NTB0104UK,012 pinout, NTB0104UK,012 application, or NTB0104UK,012 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, ±1 µA max OFF-state leakage across −40 °C to +125 °C, 4.4 ns typical A→B propagation delay at 3.3 V/3.3 V, and 7.5 pF B-port input/output capacitance enabling high-speed I/O bridging between mixed-voltage SoCs and peripherals.
Technical Context
The NTB0104UK,012 implements auto-direction sensing via edge-triggered one-shot circuits that dynamically enable PMOS/NMOS drive transistors during signal transitions-no external direction control required. Its dual-rail architecture isolates VCC(A) and VCC(B) domains, with OE referenced solely to VCC(A).
IOFF circuitry actively disables outputs when either supply drops to GND, blocking backflow current up to ±100 mA per JESD78B Class II. Input clamping supports 5.5 V tolerance on both ports independent of supply, while static drive strength is optimized for ≤70 pF capacitive loads-not open-drain buses like I²C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - enables interface with 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V logic domains |
| VCC(B) Range | 1.65 V to 5.5 V - supports translation to 1.8 V/2.5 V/3.3 V/5.0 V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E-Q1 | 4-bit, auto-direction, same VCC(A)/VCC(B) ranges; higher 10 pF B-port capacitance; 6.5 ns max tpd at 3.3 V | Qualified to AEC-Q100 Grade 1 but rated only to +105 °C ambient | Select when +125 °C operation is not required and board space allows SOIC-14 package |
| SN74AVC4T245-Q1 | 4-bit, direction-controlled (DIR pin required); lower 4.5 pF B-port capacitance; 3.2 ns max tpd at 3.3 V | Requires external direction logic; no IOFF; rated −40 °C to +125 °C | Select when deterministic low-latency (<4 ns) is critical and direction control is available in system design |
Compared with TXS0104E-Q1, NTB0104UK,012 offers extended temperature range and lower B-port capacitance; versus SN74AVC4T245-Q1, it eliminates DIR pin routing and provides IOFF protection but trades 0.8 ns propagation delay for autonomous operation.

FAQ
What is the maximum data rate supported by the NTB0104UK,012?
The NTB0104UK,012 supports up to 100 Mbps data rate under recommended operating conditions (VCC(A)=3.3 V, VCC(B)=5.0 V, Tamb=25 °C), verified by pulse width (tW ≥10 ns) and propagation delay (tpd ≤7.0 ns) specifications across the full −40 °C to +125 °C automotive temperature range.
Does the NTB0104UK,012 require external direction control signals?
No, the NTB0104UK,012 features built-in auto-direction sensing using edge-triggered one-shot circuits-no DIR pin or firmware-controlled GPIO is needed. Data flow direction is determined dynamically by signal transitions on either A or B ports, simplifying system design and reducing pin count on host processors.
Can NTB0104UK,012 operate with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously?
Yes, the NTB0104UK,012 is fully specified for simultaneous operation at VCC(A) = 1.2 V and VCC(B) = 5.0 V, delivering 4.2 ns typical A→B propagation delay and maintaining ±1 µA OFF-state leakage across −40 °C to +125 °C, as confirmed in Table 10 and Table 12 of the official datasheet.
Is the NTB0104UK,012 compatible with I²C or 1-Wire bus protocols?
No, the NTB0104UK,012 is not recommended for I²C or 1-Wire applications due to its low static drive strength and lack of open-drain support. Its design targets push-pull interfaces; for I²C, NXP recommends the NTS0104-Q100, which is explicitly optimized for open-drain topologies.
What is the purpose of the IOFF functionality in NTB0104UK,012?
The IOFF functionality in NTB0104UK,012 disables outputs and blocks backflow current when either VCC(A) or VCC(B) is at GND, preventing damage during partial power-down-essential for automotive modules with independent domain power gating. This feature is validated per JESD78B Class II latch-up immunity and ensures safe operation during battery disconnect or cold-cranking events.
