NXP Semiconductors NVT2002TLH

Overview

NVT2002TLH from NXP Semiconductors is a 2-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 operation across –40 °C to +105 °C. It enables seamless I²C bus interfacing between 1.8 V microcontrollers and 3.3 V peripherals without direction control.

For engineers reviewing the NVT2002TLH datasheet, NVT2002TLH pinout, NVT2002TLH application, or NVT2002TLH equivalent, this page delivers verified electrical parameters, package-specific pin mapping, real-world use cases in mixed-voltage digital systems, and two validated alternative parts with documented functional and layout implications.

Technical Context

The NVT2002TLH implements a passive MOSFET-based clamping architecture with no internal direction pin-translation direction is determined dynamically by relative voltage levels on A- and B-side ports. Each channel features symmetrical Ron (≤5.0 Ω) and matched propagation delay (<1.5 ns), ensuring minimal skew between A1↔B1 and A2↔B2 paths.

EN is referenced to V_REF(B), requiring V_REF(B) ≥ V_REF(A) + 1 V for reliable enable/disable control. When EN = HIGH, low-impedance conduction occurs; when EN = LOW, both An and Bn pins enter high-impedance state. The device supports up to 33 MHz operation under 50 pF load with 197 Ω pull-up.

FAQ

What is the maximum operating frequency supported by the NVT2002TLH?

The NVT2002TLH supports up to 33 MHz in open-drain systems with 50 pF load and 197 Ω pull-up resistors, as confirmed in the datasheet's dynamic characteristics section. Real-world frequency depends on total node capacitance, driver strength, and pull-up resistor selection-designers should validate timing margins using the RC-based rise/fall time equations provided in Section 7.4 of the NVT2002TLH datasheet.

Can the NVT2002TLH replace the discontinued NVT2002GD without PCB changes?

Yes-the NVT2002TLH is explicitly designated as the drop-in replacement for NVT2002GD per Discontinuation Notice 202111012DN. Its HXSON8 package shares identical 3 mm × 2 mm outline and pin positions; the center thermal pad is non-electrical and may be left floating or connected to GND without affecting functionality, making it compatible with existing GD footprints.

What are the voltage requirements for the EN pin on the NVT2002TLH?

The EN pin on the NVT2002TLH must be driven by V_REF(B) (1.8–5.5 V) and pulled up via a 200 kΩ resistor to V_PU(D). For reliable operation, V_REF(B) must be at least 1 V higher than V_REF(A), and VI(EN) must remain within 0–5.5 V. EN = LOW places all I/Os in high-impedance state during power-up or shutdown.

Does the NVT2002TLH support push-pull drivers, or is it limited to open-drain applications?

The NVT2002TLH supports both open-drain and push-pull drivers, as stated in the General Description. For push-pull use, outputs must be 3-stateable or unidirectional to prevent contention; for open-drain, no direction control is needed. The device's clamping architecture inherently handles bidirectional signal flow regardless of driver type, provided proper pull-up configuration and voltage margining.

How does the center thermal pad on the NVT2002TLH affect thermal performance and PCB layout?

The center thermal pad on the NVT2002TLH is electrically isolated from the die and serves only mechanical and thermal functions. It improves heat dissipation in high-density layouts but may be left floating or connected to GND-no electrical connection is required. Unlike the NVT2002GD, the TL package's pad allows enhanced thermal reliability without altering signal routing or requiring redesign of the GD footprint.
