Nexperia USA Inc. 74LV02APWJ

Overview

74LV02APWJ from Nexperia is a quad 2-input NOR gate logic IC in TSSOP14 package, operating from 2.0 V to 5.5 V supply, with 10 ns max propagation delay at 5 V, overvoltage-tolerant inputs for mixed-voltage translation, and IOFF-enabled partial power-down protection. It serves as a level-shifting combinational logic element in interface bridging and control signal conditioning circuits.

For engineers reviewing the 74LV02APWJ datasheet, 74LV02APWJ pinout, 74LV02APWJ application, or 74LV02APWJ equivalent, this device is selected for robustness in mixed-supply systems, Schmitt-trigger noise immunity on all inputs, and guaranteed operation across -40 °C to +125 °C industrial temperature range.

Technical Context

The 74LV02APWJ implements four independent 2-input NOR gates with Schmitt-trigger inputs, enabling tolerance of slow-rising/falling signals and improved noise rejection. Each gate exhibits symmetrical HIGH/LOW output drive capability up to ±35 mA per output.

Its IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail system designs. Input voltage tolerance extends to -0.5 V to +7.0 V, supporting safe interfacing between 3.3 V and 5 V domains without external clamping.

FAQ

Can 74LV02APWJ safely interface a 5 V microcontroller GPIO to a 3.3 V FPGA input?

Yes. Its inputs tolerate up to +7.0 V regardless of VCC, allowing direct connection of 5 V signals while powered from 3.3 V. No external level shifter or clamping diode is needed, and Schmitt-trigger action rejects noise on the 5 V line.

Does 74LV02APWJ support hot-swap insertion when other system rails remain active?

Yes. The IOFF circuit disables outputs when VCC = 0 V, preventing back-current from live inputs into the unpowered device. This protects both the IC and upstream drivers during live insertion or rail sequencing faults.

What is the minimum supply voltage at which 74LV02APWJ guarantees correct logic operation?

The device is fully specified from 2.0 V to 5.5 V. At 2.0 V, propagation delay increases to ≤200 ns/V (per Table 5), and output drive weakens, but logic thresholds and function remain valid down to 2.0 V across the full -40 °C to +125 °C range.

How does the Schmitt-trigger input improve performance in noisy industrial environments?

Schmitt-trigger inputs provide hysteresis (typically ~0.3 V at 3.3 V), meaning the rising and falling input thresholds differ. This prevents multiple toggles on slow or noisy edges - critical for reliable debouncing of mechanical switch inputs or long cable runs in factory automation.
