NXP Semiconductors NVT2006BSHP

Overview

NVT2006BSHP from NXP Semiconductors is a 6-bit bidirectional voltage-level translator IC for open-drain and push-pull applications, supporting V_REF(A) from 1.0 V to 3.6 V and V_REF(B) from 1.8 V to 5.5 V, with ≤1.5 ns max propagation delay, 3.5 Ω typical ON-state resistance, and 5 V-tolerant I/O - deployed in I²C bus interfacing between 1.8 V microcontrollers and 3.3 V/5 V peripherals.

For engineers reviewing the NVT2006BSHP datasheet, NVT2006BSHP pinout, NVT2006BSHP application, or NVT2006BSHP equivalent, key selection criteria include its direction-pin-free bidirectional operation, flow-through pinout for PCB routing efficiency, EN-controlled high-impedance disable state, ESD robustness (3.5 kV HBM), and compatibility with mixed-voltage domains in industrial control and embedded sensor interfaces.

Technical Context

The NVT2006BSHP implements a passive MOSFET-based clamping architecture: when either A_n or B_n is LOW, the internal switch turns ON, establishing a low-R_on path (<5 Ω) between ports; when A_n is HIGH, B_n is pulled to V_PU(D) via external pull-up resistors, enabling seamless up-translation without directional control.

EN is referenced to V_REF(B) and must be ≥1 V above V_REF(A) for reliable operation; all six channels share identical electrical characteristics, minimizing inter-channel skew and ensuring consistent timing across I/O pairs - critical for multi-line buses like I²C and SMBus.

FAQ

What is the minimum voltage difference required between VREF(A) and VREF(B) for reliable operation of the NVT2006BSHP?

The NVT2006BSHP requires V_REF(B) to be at least 1 V higher than V_REF(A) for best translator operation, as specified in the datasheet's application conditions table. This ensures proper clamp transistor biasing and avoids undefined states during voltage transitions. For example, pairing V_REF(A) = 1.8 V with V_REF(B) = 3.3 V meets this requirement, while 1.8 V/2.5 V does not and may cause incomplete translation or increased propagation delay.

Can the NVT2006BSHP be used with push-pull drivers on both A-side and B-side simultaneously?

Yes, the NVT2006BSHP supports push-pull drivers on both sides, but only if outputs are 3-stateable and externally coordinated to prevent HIGH-to-LOW contention. The datasheet explicitly warns that uncontrolled simultaneous drive from both sides risks bus conflict. In practice, this means using the EN pin or external direction logic to ensure only one side drives at a time - unlike open-drain configurations, which inherently avoid contention.

Does the NVT2006BSHP require external pull-up resistors on both A-side and B-side I/O lines?

External pull-up resistors are mandatory on the B-side (V_REF(B) domain) for proper HIGH-level translation, and recommended on the A-side only when interfacing with open-drain drivers. The datasheet provides minimum resistor values (e.g., 1.47 kΩ for 1.8 V→3.3 V at 3 mA sink) based on driver strength and target frequency. No internal pull-ups exist - all pull-up functionality is external and configurable per application.

How does the EN pin function, and what voltage levels are valid for enabling the NVT2006BSHP?

The EN pin is referenced to V_REF(B) and must be driven to a logic HIGH level ≥1 V above V_REF(A) (typically ≥2.1 V when V_REF(A) = 1.0 V) to activate translation. It is not TTL- or CMOS-compatible by default - correct operation requires pulling EN to V_REF(B) via a resistor (e.g., 200 kΩ). When EN is LOW, all 12 I/Os enter high-impedance, fully isolating the A- and B-domains.

Is the NVT2006BSHP pin-compatible with other members of the NVT200x family, such as NVT2006BQ or NVT2006PW?

No, the NVT2006BSHP (HVQFN16) is not pin-compatible with NVT2006BQ (DHVQFN16) or NVT2006PW (TSSOP16): although all are 6-bit translators, their pinouts differ significantly - e.g., GND is pin 15 in HVQFN16 but pin 1 in DHVQFN16, and V_REF(A) is pin 16 in HVQFN16 but pin 2 in TSSOP16. PCB layout must be redesigned for each package variant; no mechanical or electrical drop-in replacement exists.
