Nexperia USA Inc. 74LVC2G02DP,125

Overview

74LVC2G02DP,125 from Nexperia is a dual 2-input NOR gate logic IC in TSSOP8 (SOT505-2) package, operating from 1.65 V to 5.5 V supply, featuring 5 V-tolerant inputs/outputs, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity in mixed-voltage digital interfaces.

For engineers reviewing the 74LVC2G02DP,125 datasheet, 74LVC2G02DP,125 pinout, 74LVC2G02DP,125 application, or 74LVC2G02DP,125 equivalent, this device serves as a voltage-translating logic gate in level-shifting I/O buffers, reset signal conditioning, and enable control circuits where robustness against slow edges and power sequencing is required.

Technical Context

This device implements two independent CMOS NOR gates with rail-to-rail input voltage tolerance up to 5.5 V and guaranteed operation down to 1.65 V. Each gate features Schmitt-trigger inputs with hysteresis, enabling reliable switching despite slow or noisy input transitions.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and multi-rail system designs. Propagation delay ranges from 0.6 ns (at 5 V) to 11.2 ns (at 1.65 V, –40 °C to +125 °C), supporting both high-speed and ultra-low-voltage operation.

FAQ

Can 74LVC2G02DP,125 operate with VCC = 1.8 V while accepting 3.3 V inputs?

Yes. The device is fully specified from 1.65 V to 5.5 V supply and supports overvoltage-tolerant inputs up to 5.5 V. At VCC = 1.8 V, VIH is 0.65 × VCC ≈ 1.17 V and VIL is 0.35 × VCC ≈ 0.63 V, ensuring reliable recognition of 3.3 V logic levels as HIGH without damage or undefined behavior.

Does the IOFF feature work when only one supply rail is powered down?

Yes. IOFF activates whenever VCC = 0 V, regardless of input/output voltage states. With VCC unpowered, outputs are high-impedance and leakage remains ≤±2 μA-even if 5 V signals are applied to inputs or outputs-preventing back-current paths in partial-power-down scenarios.

What is the maximum capacitive load this device can drive at 10 MHz?

Based on CPD = 14 pF per gate and dynamic power formula PD = CPD × VCC² × fi × N, at VCC = 3.3 V and fi = 10 MHz, dynamic dissipation is ~1.5 mW per gate. With typical PCB trace capacitance < 5 pF and recommended CL ≤ 50 pF, the device reliably drives loads up to 30–40 pF at 10 MHz without exceeding thermal limits in TSSOP8.

Is the 74LVC2G02DP,125 qualified for automotive applications?

No. While rated for –40 °C to +125 °C, this variant is not AEC-Q100 qualified and lacks automotive-specific testing (e.g., HTOL, ESD stress beyond HBM 2 kV). Nexperia offers automotive-grade equivalents (e.g., 74LVC2G02DP/AU) with full qualification-this part is intended for industrial, computing, and consumer use.
