Nexperia USA Inc. 74LVT02PW,112

Overview

74LVT02PW,112 from Nexperia is a 3.3 V quad 2-input NOR gate in TSSOP14 package, designed for high-speed logic interfacing with ±32 mA/±64 mA drive capability, IOFF-enabled partial power-down protection, and 5.5 V-tolerant inputs. It operates across -40 °C to +85 °C and supports direct TTL-level interface in bus-hold or hot-swap-capable digital subsystems.

For engineers reviewing the 74LVT02PW,112 datasheet, 74LVT02PW,112 pinout, 74LVT02PW,112 application, or 74LVT02PW,112 equivalent, this device is selected for low-voltage logic translation, bus isolation in mixed-supply systems, and noise-immune control signal conditioning where I_OFF current limiting and overvoltage input tolerance are critical.

Technical Context

The 74LVT02PW,112 implements four independent NOR gates with complementary CMOS output stages, each supporting asymmetrical drive strength (−32 mA HIGH, +64 mA LOW) to optimize rise/fall time balance on capacitive loads. Its IOFF circuit actively disables outputs during V_CC = 0 V, blocking backflow current when connected to live 5 V buses.

Input clamping diodes allow safe operation with 5.5 V signals while powered from 3.3 V, and propagation delays are specified at 2.6–4.4 ns (t_PHL/t_PLH) under 3.0–3.6 V supply, enabling reliable timing in sub-200 MHz synchronous logic paths.

FAQ

Can 74LVT02PW,112 safely interface with 5 V microcontroller outputs?

Yes. Its inputs tolerate up to 5.5 V regardless of V_CC level, and internal clamping diodes limit current to safe levels. No external resistors or level shifters are required when connecting to standard 5 V TTL or CMOS outputs, provided V_CC remains within 2.7–3.6 V.

What happens to outputs during power-down?

When V_CC drops to 0 V, the IOFF circuit activates and forces all outputs into high-impedance state with leakage ≤±100 μA. This prevents backflow current into the device from live 5 V buses, protecting both the gate and upstream drivers during partial power-down sequences.

Is thermal derating required for continuous operation at 85 °C?

Yes. For the TSSOP14 (SOT402-1) package, total power dissipation derates linearly at 7.3 mW/K above 81 °C. At 85 °C ambient, maximum P_tot is reduced to approximately 471 mW from the 500 mW rated value-sufficient for typical logic loading but requires verification under worst-case I_OL/I_OH conditions.

How does its propagation delay compare to 74LVC02 variants?

At 3.3 V, 74LVT02PW,112 exhibits t_PHL = 2.6 ns and t_PLH = 2.8 ns, slightly slower than 74LVC02's ~2.1 ns but significantly faster than older 74HC02 (~15 ns). The LVT variant prioritizes drive strength and voltage tolerance over minimal delay, making it more suitable for loaded or mixed-voltage interconnects.
