Nexperia USA Inc. 74LVC2G02GN,115

Overview

74LVC2G02GN,115 from Nexperia is a dual 2-input NOR gate logic IC in XSON8 (SOT1116) 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 74LVC2G02GN,115 datasheet, 74LVC2G02GN,115 pinout, 74LVC2G02GN,115 application, or 74LVC2G02GN,115 equivalent, this device serves as a voltage-translating logic gate in level-shifting, signal conditioning, and bus arbitration circuits where robust input timing and power-down isolation are required.

Technical Context

The 74LVC2G02GN implements two independent 2-input NOR gates with rail-to-rail CMOS output stages, each supporting bidirectional voltage translation between 1.65 V and 5.5 V domains. Its Schmitt-trigger inputs provide hysteresis (typ. 0.2 V at VCC = 3.3 V), enabling reliable operation with slow-rising signals.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA, making it suitable for hot-swap and partial-power-down systems. Propagation delay ranges from 0.6 ns (VCC = 5.5 V) to 11.2 ns (VCC = 1.65 V, -40 °C to +125 °C), with 14 pF power dissipation capacitance per gate.

FAQ

Can 74LVC2G02GN,115 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device supports 5.5 V overvoltage-tolerant inputs across its entire 1.65 V–5.5 V supply range. At VCC = 1.65 V, inputs up to 5.5 V are safely clamped internally without damage or functional degradation, enabling robust level shifting from 5 V peripherals to low-voltage controllers.

What is the maximum capacitive load the outputs can drive at 3.3 V supply?

At VCC = 3.3 V, the 74LVC2G02GN,115 can reliably drive up to 30 pF with guaranteed 2.4 ns typical propagation delay (tPLH/tPHL) and <0.55 V VOL at 24 mA sink current. For loads exceeding 30 pF, series termination or buffer staging is recommended to maintain timing integrity.

Does the IOFF feature require external biasing or control signals?

No. IOFF activates automatically when VCC drops to 0 V - no external enable/disable pin or configuration is needed. Output terminals enter high-impedance state with ≤±2 μA leakage, preventing back-current flow even if input/output pins remain at 5 V during power-down sequences.

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

Schmitt-trigger inputs provide ~0.2 V hysteresis (e.g., VIH ≈ 1.7 V, VIL ≈ 1.5 V at VCC = 3.3 V), rejecting transient noise spikes and slow-rising signals that could cause metastability or false triggering in standard CMOS inputs - critical for switch debouncing and long-trace routing.
