NXP Semiconductors NVT2010BQ,118

Overview

NVT2010BQ,118 from NXP Semiconductors is a 10-bit bidirectional voltage-level translator IC enabling seamless signal translation between 1.0 V–3.6 V (Vref(A)) and 1.8 V–5.5 V (Vref(B)) domains without direction control. It features ≤1.5 ns max propagation delay, 3.5 Ω typical ON-state resistance, 5 V-tolerant I/Os, and supports open-drain and push-pull interfaces in industrial I²C, SMBus, and GPIO interconnect applications.

For engineers reviewing the NVT2010BQ,118 datasheet, NVT2010BQ,118 pinout, NVT2010BQ,118 application, or NVT2010BQ,118 equivalent, key selection criteria include verified bidirectional operation without direction pin, EN-controlled high-impedance disable, flow-through pinout for PCB routing, ESD robustness (4 kV HBM), and compatibility with mixed-voltage SoC-to-peripheral interfacing under −40 °C to +85 °C.

Technical Context

The NVT2010BQ,118 implements a passive MOSFET-based clamping architecture where each A/B channel pair forms a symmetrical bidirectional switch controlled by Vref(A) and Vref(B). Its EN input-supplied by Vref(B)-enables/disables all 10 channels simultaneously into low- or high-impedance states.

Operation relies on voltage-dependent clamp conduction: when An is LOW, the internal switch connects An–Bn with Ron ≈ 3.5 Ω; when An is HIGH and Bn is pulled up via external resistor to Vpu(D), the output voltage at An is clamped to Vref(A), while Bn rises to Vpu(D). This enables true bidirectional level shifting without timing skew or lock-up.

FAQ

What voltage ranges does the NVT2010BQ,118 support for bidirectional level translation?

The NVT2010BQ,118 supports Vref(A) from 1.0 V to 3.6 V and Vref(B) from 1.8 V to 5.5 V. Valid translation combinations include 1.0 V ↔ 1.8 V/2.5 V/3.3 V/5 V, 1.2 V ↔ same B-side voltages, 1.8 V ↔ 3.3 V/5 V, 2.5 V ↔ 5 V, and 3.3 V ↔ 5 V. The NVT2010BQ,118 requires Vref(B) to be at least 1 V higher than Vref(A) for reliable operation per datasheet Section 6.1.

Does the NVT2010BQ,118 require external pull-up resistors, and if so, where?

Yes-the NVT2010BQ,118 requires external pull-up resistors on all Bn pins (and optionally on An pins depending on driver type). For open-drain operation, 200 kΩ pull-ups to Vpu(D) are recommended on Bn lines per Figure 7 and Section 7.2. An pins only need pull-ups if driven by open-drain sources; push-pull drivers do not require them. The NVT2010BQ,118 itself contains no internal pull-ups.

How does the EN pin function on the NVT2010BQ,118, and what voltage levels are valid?

The EN pin on the NVT2010BQ,118 is an active-HIGH enable referenced to Vref(B), not Vcc or GND. It must be driven between Vref(A)+0.6 V (min) and Vref(B) (max), with recommended operation ≥1 V above Vref(A). When EN = LOW, all A/B pins enter high-impedance state-critical for power sequencing. The NVT2010BQ,118 EN circuit is designed exclusively for Vref(B)-domain logic.

Can the NVT2010BQ,118 be used in push-pull applications, and what design precautions apply?

Yes-the NVT2010BQ,118 supports push-pull drivers on either side, but unidirectional data flow or 3-state control is mandatory to avoid HIGH-to-LOW contention. If both A and B sides use push-pull outputs, direction must be externally managed (e.g., via MCU GPIO control) since the NVT2010BQ,118 provides no built-in direction arbitration. The NVT2010BQ,118 is inherently safe with open-drain configurations without such constraints.

What is the maximum operating frequency of the NVT2010BQ,118, and what limits it?

The NVT2010BQ,118 supports up to 33 MHz in open-drain systems with 50 pF load and 197 Ω pull-up (per datasheet Section 1). Maximum frequency is limited by RC time constants involving pull-up resistance, total node capacitance (PCB + device), and driver sink strength-not by internal propagation delay (≤1.5 ns). Rise/fall times dominate; optimizing RPU and minimizing CL is essential to achieve >10 MHz operation.
