Nexperia USA Inc. 74LVC2G00GXX

Overview

74LVC2G00 from Nexperia is a dual 2-input NAND gate logic IC designed for level translation between 3.3 V and 5 V systems, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operation across 1.65 V to 5.5 V supply. It enables robust signal conditioning in mixed-voltage digital interfaces such as I²C bus buffers and microcontroller GPIO expanders.

For engineers reviewing the 74LVC2G00 datasheet, 74LVC2G00 pinout, 74LVC2G00 application, or 74LVC2G00 equivalent, key selection criteria include its 5 V-tolerant inputs/outputs, -40 °C to +125 °C industrial temperature range, sub-1 ns propagation delay at 5 V, IOFF-enabled hot-swap capability, and compatibility with JEDEC JESD8-7/5/B standards for low-voltage logic interoperability.

Technical Context

This device implements two independent CMOS NAND gates with identical truth table behavior (L/L→H, L/H→H, H/L→H, H/H→L) and Schmitt-trigger input thresholds that tolerate slow-rising/falling edges without oscillation. Each gate supports bidirectional voltage translation due to 5.5 V overvoltage-tolerant inputs and outputs.

The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA, enabling safe insertion/removal in live backplane or hot-swap applications. Static input leakage remains ≤±1 μA across full temperature and supply ranges, supporting low-power always-on monitoring circuits.

FAQ

Can 74LVC2G00 operate reliably with VCC = 1.65 V while driving 5 V inputs?

Yes. At VCC = 1.65 V, the device accepts input voltages up to 5.5 V and maintains VIH ≥0.65 × VCC (≥1.07 V) and VIL ≤0.35 × VCC (≤0.58 V), ensuring correct logic interpretation of 5 V TTL/CMOS signals without damage or misinterpretation.

Does IOFF functionality require external pull-up or pull-down resistors?

No. The IOFF circuit internally forces outputs into high-impedance state when VCC = 0 V, with leakage limited to ±2 μA. No external resistors are needed-outputs float safely, eliminating risk of contention on shared buses during power sequencing.

What is the maximum capacitive load the 74LVC2G00 can drive at 3.3 V while maintaining 1 ns propagation delay?

At VCC = 3.3 V and Tamb = 25 °C, the typical propagation delay remains ≤1 ns for loads ≤15 pF (including trace and probe capacitance), as verified by test conditions in Table 10 using 500 Ω termination and 30–50 pF CL.

How does Schmitt-trigger action improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide ≥0.4 V hysteresis at 3.3 V supply, meaning the rising threshold (VIH) is ~1.9 V and falling threshold (VIL) is ~1.5 V. This prevents multiple transitions on slowly changing or noisy signals-such as mechanical switch bounce or EMI-coupled traces-ensuring single, clean logic edges.
