NXP Semiconductors NVT2004TL,115

Overview

NVT2004TL,115 from NXP Semiconductors is a 4-bit bidirectional voltage-level translator supporting 1.0 V to 3.6 V (Vref(A)) and 1.8 V to 5.5 V (Vref(B)) domains, enabling seamless open-drain and push-pull level translation without direction control. It delivers ≤1.5 ns max propagation delay, 3.5 Ω typical ON-state resistance, and operates across –40 °C to +85 °C for I²C bus interfacing between 1.8 V microcontrollers and 3.3 V peripherals.

For engineers reviewing the NVT2004TL,115 datasheet, NVT2004TL,115 pinout, NVT2004TL,115 application, or NVT2004TL,115 equivalent, key selection criteria include its flow-through TSSOP14 pinout, 5 V-tolerant I/Os, EN-controlled high-impedance state, ESD robustness (3.5 kV HBM), and compatibility with mixed-voltage I²C, SMBus, and GPIO interconnects in space-constrained embedded systems.

Technical Context

The NVT2004TL,115 implements a passive clamp-based bidirectional translation architecture where each A/B channel pair forms a low-Ron MOS switch controlled by Vref(A) and Vref(B). When either port is LOW, the internal clamp activates, establishing a low-impedance path; when HIGH, the opposite port is pulled up via external resistors. EN is referenced to Vref(B) and must be ≥1 V above Vref(A) for reliable operation.

Unlike direction-pin translators, it requires no control logic overhead and supports simultaneous up-translation (A→B) and down-translation (B→A) on all four channels. Its symmetrical fabrication ensures matched propagation delay (<0.2 ns skew) and uniform voltage thresholds across all bits-critical for timing-sensitive multi-line buses like I²C SCL/SDA pairs.

FAQ

What is the maximum supported data rate for NVT2004TL,115 in an open-drain I²C configuration?

The NVT2004TL,115 supports >33 MHz operation with a 50 pF bus capacitance and 197 Ω pull-up resistor, based on its ≤1.5 ns propagation delay and low 3.5 Ω ON-resistance. Real-world I²C performance depends on total node capacitance and driver strength - for standard-mode (100 kHz) or fast-mode (400 kHz) I²C, the NVT2004TL,115 imposes negligible timing overhead and fully complies with JEDEC SMBus specifications.

Can NVT2004TL,115 translate between 1.0 V and 5.0 V logic levels?

Yes - the NVT2004TL,115 explicitly supports Vref(A) = 1.0 V and Vref(B) = 5.0 V, provided Vref(B) ≥ Vref(A) + 1 V (per datasheet requirement). In this configuration, A-port outputs are clamped to 1.0 V, while B-port outputs swing to 5.0 V via external pull-ups. The device's 5 V-tolerant I/Os and 3.5 kV HBM ESD rating ensure safe operation across this full range.

How should the EN pin be connected for reliable operation of NVT2004TL,115?

The EN pin of NVT2004TL,115 must be referenced to Vref(B) and pulled HIGH through a resistor (typically 200 kΩ) to Vpu(D). It must remain ≥1 V above Vref(A) during active operation. During power-up/power-down, EN should be held LOW (e.g., via RC network or processor GPIO) to ensure all I/Os enter high-impedance state before valid Vref voltages stabilize - preventing bus contention.

Does NVT2004TL,115 require external pull-up resistors on both sides of the interface?

Yes - external pull-up resistors are mandatory on both A and B sides for open-drain operation. For push-pull drivers, pull-ups are required only on the side receiving open-drain signals. Resistor values depend on bus capacitance, sink current, and speed; Table 6–8 in the NXP datasheet provides validated minimum values (e.g., 887 Ω for 1.8 V → 3.3 V at 3 mA sink).

Is NVT2004TL,115 compatible with hot-swap or partial-power-down scenarios?

Yes - the NVT2004TL,115 features lock-up free operation and is designed for robust power sequencing. When one domain powers down, the clamp structure inherently isolates the live side. With EN tied to Vref(B), loss of Vref(B) forces high-impedance mode, protecting powered-down logic. This makes NVT2004TL,115 suitable for hot-pluggable modules and domain-isolated subsystems.
