Product details

Overview

NTS0304EPWJ from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in TSSOP14 package, supporting open-drain I²C/SMBus and GPIO interfaces between 0.95 V–3.6 V (A-side) and 1.65 V–5.5 V (B-side) domains. It enables seamless interoperation between mixed-voltage subsystems such as 1.8 V microcontrollers and 3.3 V sensors without external direction control.

For engineers reviewing the NTS0304EPWJ datasheet, NTS0304EPWJ pinout, NTS0304EPWJ application, or NTS0304EPWJ equivalent, this page delivers verified electrical parameters, thermal performance at −40 °C to +125 °C, open-drain data rate up to 2 Mbps, push-pull data rate up to 20 Mbps, and real-world ESD robustness per IEC 61000-4-2 Class 4 (8 kV contact on B-side).

Technical Context

The NTS0304EPWJ implements a pass-gate architecture with integrated one-shot edge acceleration and slew-rate control. Its auto-direction sensing eliminates need for external DIR signal, while internal 10 kΩ pull-ups on both A and B ports simplify I²C bus implementation.

Each I/O pair operates as a bidirectional switch with gate bias set ~1 V_TH above the lower supply rail. The one-shot circuit activates on input transitions crossing V_CCI/2 and sustains ~50 ns to drive heavy capacitive loads-reducing ringing and overshoot without external components.

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 (Texas Instruments)	Same 4-bit auto-direction architecture; VCC(A): 1.2–3.6 V, VCC(B): 1.65–5.5 V; no B-side IEC 61000-4-2 certification	Lacks 8 kV contact ESD rating on B-side - requires external protection for hot-plug use cases	Select when cost sensitivity outweighs system-level ESD compliance requirements
PCA9306 (NXP)	2-bit only; no OE pin; VCC(A): 1.2–3.6 V, VCC(B): 1.8–5.5 V; lacks one-shot acceleration	Lower channel count and no enable control - unsuitable for GPIO expansion or partial-bus isolation	Select only for simple 2-wire I²C translation where OE gating and 4-channel density are unnecessary

Compared with TXS0104E and PCA9306, the NTS0304EPWJ uniquely combines 4-channel density, active OE control, 8 kV B-side ESD hardening, and one-shot-driven edge acceleration - making it optimal for space-constrained, high-reliability mixed-voltage interfaces demanding both speed and ruggedness.

FAQ

What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0304EPWJ?

The NTS0304EPWJ requires VCC(A) ≤ VCC(B) at all times during active operation. While VCC(A) may temporarily exceed VCC(B) during power-up without damage, sustained operation with VCC(A) > VCC(B) risks latch-up and undefined behavior. The absolute maximum ratings allow VCC(A) up to +4.6 V and VCC(B) up to +6.5 V independently, but functional operation is guaranteed only when VCC(A) remains within 0.95 V to 3.6 V and VCC(B) within 1.65 V to 5.5 V, with VCC(A) ≤ VCC(B). This constraint ensures correct gate biasing of the internal pass transistor in the NTS0304EPWJ.

Does the NTS0304EPWJ support true push-pull driving on both A and B ports, or is it limited to open-drain operation?

The NTS0304EPWJ supports both open-drain and push-pull operation on all A and B ports. Its internal architecture uses a pass-gate transistor that conducts bidirectionally, allowing either side to actively drive HIGH (via external pull-up) or LOW (via internal NMOS sink), or to be driven by an external push-pull source. The datasheet specifies 20 Mbps maximum data rate under push-pull conditions - confirmed across VCC(A)/VCC(B) combinations including 1.8 V/3.3 V and 3.3 V/5.0 V. This capability makes the NTS0304EPWJ suitable for UART, SPI, and general-purpose GPIO translation beyond I²C.

How does the one-shot accelerator circuit in the NTS0304EPWJ improve signal integrity compared to standard level translators?

The one-shot accelerator in the NTS0304EPWJ delivers a timed ~50 ns current boost during rising-edge transitions, reducing output rise time and suppressing ringing caused by trace inductance and load capacitance. Unlike passive translators, it dynamically increases drive strength only when needed - lowering EMI while avoiding overshoot. Test data shows tTLH reduced by up to 40% versus non-accelerated devices under 100 pF load. This feature is intrinsic to the NTS0304EPWJ's architecture and requires no external components or configuration.

Can the NTS0304EPWJ be used in systems where the A-side and B-side supplies are powered from independent regulators with no shared sequencing?

Yes - the NTS0304EPWJ explicitly requires no power-sequencing. Either VCC(A) or VCC(B) may be powered first, and the device enters a safe high-impedance state if either supply drops to GND. Internal power-down detection disables all I/Os automatically, preventing back-powering or contention. This behavior is validated across −40 °C to +125 °C and is a defined feature of the NTS0304EPWJ, not a failure-mode safeguard.

What is the role of the internal 10 kΩ pull-up resistors on the A and B ports of the NTS0304EPWJ, and can they be disabled?

The internal 10 kΩ pull-up resistors on both A and B ports provide DC current sourcing for open-drain protocols like I²C, eliminating need for external resistors. They are tied to their respective VCC rails (VCC(A) for A-port, VCC(B) for B-port) and are automatically disabled when OE is driven LOW - placing all I/Os in high-impedance state. These resistors cannot be permanently disabled via configuration; however, external lower-value pull-ups may be added in parallel if faster rise times are required, as the NTS0304EPWJ tolerates 3.6 V on A-side and 5.5 V on B-side inputs.
