NXP Semiconductors NVT2006BS,118

Overview

NVT2006BS,118 from NXP Semiconductors is a 6-bit bidirectional voltage-level translator IC for open-drain and push-pull applications, operating between 1.0 V–3.6 V (Vref(A)) and 1.8 V–5.5 V (Vref(B)), with ≤1.5 ns max propagation delay, 3.5 Ω typical ON-state resistance, and 5 V-tolerant I/Os. It enables seamless level translation in I²C bus interfaces between 1.8 V processors and 3.3 V/5 V peripherals without direction control.

For engineers reviewing the NVT2006BS,118 datasheet, NVT2006BS,118 pinout, NVT2006BS,118 application, or NVT2006BS,118 equivalent, key selection criteria include its flow-through HVQFN16 pinout, EN-controlled high-impedance disable state, ESD robustness (3.5 kV HBM), and support for mixed-voltage domains in industrial and embedded communication subsystems.

Technical Context

The NVT2006BS,118 implements a passive clamp-based bidirectional translation architecture: when either An or Bn port is LOW, the internal MOSFET switch turns ON, establishing a low-Ron path (<5 Ω) between ports; when HIGH, voltage clamping is enforced by Vref(A) or external pull-up (Vpu(D)). Its EN input-supplied by Vref(B)-controls global enable/disable with no need for level-shifting on the control line.

Unlike directional translators, it requires no timing-critical direction signal and supports both open-drain (e.g., I²C SCL/SDA) and push-pull topologies. All six channels share matched electrical characteristics, minimizing inter-channel skew and ensuring consistent propagation delay (<1.5 ns) and voltage translation accuracy across the full operating temperature range (−40 °C to +85 °C).

FAQ

What is the maximum supported data rate for NVT2006BS,118 in an I²C open-drain configuration?

The NVT2006BS,118 supports transmission speeds up to 33 MHz in open-drain systems with 50 pF bus capacitance and 197 Ω pull-up resistors. Real-world I²C Fast Mode Plus (1 Mbps) and custom high-speed GPIO applications are reliably achieved; actual maximum frequency depends on total node capacitance, pull-up strength, and driver sink current per the datasheet's RC-based timing model.

Can NVT2006BS,118 translate between 1.0 V and 5.0 V domains?

Yes, the NVT2006BS,118 explicitly supports 1.0 V Vref(A) and 5.0 V Vref(B) translation per the product data sheet. To ensure reliable operation, Vref(B) must be at least 1 V higher than Vref(A), and EN must be supplied from Vref(B) with appropriate pull-up. The 5 V-tolerant B-side I/Os safely interface with 5 V peripherals without external protection.

How does the EN pin function on NVT2006BS,118, and what happens when it is left floating?

The EN pin on NVT2006BS,118 is an active-HIGH enable referenced to Vref(B). When EN is LOW, all I/Os enter high-impedance state; when HIGH, bidirectional translation is active. Leaving EN floating is not permitted-it must be pulled HIGH to Vref(B) via a resistor (e.g., 200 kΩ) to guarantee defined operation and prevent unintended disable during power-up.

Is NVT2006BS,118 compatible with push-pull drivers, or only open-drain?

The NVT2006BS,118 supports both open-drain and push-pull applications. For push-pull use, outputs must be 3-stateable or unidirectional to avoid contention; the device itself does not enforce directionality. Its low Ron and fast propagation make it suitable for push-pull GPIO, reset, and UART signal translation when properly configured per Section 7.2 of the datasheet.

What thermal considerations apply to NVT2006BS,118 in continuous 6-channel operation?

The NVT2006BS,118 uses an HVQFN16 package with an exposed thermal pad for efficient heat dissipation. Under worst-case conditions (64 mA per channel, 85 °C ambient), junction temperature remains within spec due to its low 3.5 Ω Ron and thermal design. For sustained high-current operation, PCB layout must include adequate copper pour connected to the thermal pad per NXP's recommended footprint in SOT758-1.
