NXP Semiconductors 74LVC2G02GF,115

Overview

74LVC2G02GF,115 from Nexperia is a dual 2-input NOR gate logic IC designed for level translation between 3.3 V and 5 V domains, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operation across -40 °C to +125 °C. It enables robust signal conditioning in mixed-voltage microcontroller I/O expansion and bus interface circuits.

For engineers reviewing the 74LVC2G02GF,115 datasheet, 74LVC2G02GF,115 pinout, 74LVC2G02GF,115 application, or 74LVC2G02GF,115 equivalent, key selection criteria include its 1.65–5.5 V supply range, 5 V-tolerant outputs, overvoltage-tolerant inputs up to 5.5 V, IOFF-enabled hot-swap capability, and XSON8 (SOT1089) package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent CMOS NOR gates with Schmitt-trigger input thresholds, enabling reliable operation with slow-rising or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for live-insertion and partial-power-down systems.

All inputs tolerate voltages up to 5.5 V regardless of VCC, and outputs drive 5 V TTL/CMOS loads while powered from as low as 1.65 V. Propagation delay ranges from 0.6 ns (VCC = 5.5 V) to 11.2 ns (VCC = 1.65 V, -40 °C to +85 °C), supporting both high-speed control and low-power standby modes.

FAQ

Can 74LVC2G02GF,115 operate with VCC = 1.65 V while driving a 5 V load?

Yes - its outputs are 5 V tolerant, meaning they can safely sink or source current into a 5 V rail even when powered from 1.65 V. The output high voltage (VOH) will be ~1.55 V at 1.65 V VCC and 4 mA load, sufficient to meet VIH of downstream 1.8 V or 2.5 V devices. However, it cannot actively drive a 5 V logic high level; external pull-up is required for true 5 V output swing.

Does the IOFF feature require external control signals?

No - IOFF is fully automatic and requires no external enable/disable pins. When VCC drops to 0 V (or near 0 V), the internal circuitry detects the loss of supply and forces all outputs into high-impedance state within nanoseconds, preventing back-current flow from powered I/O lines into the unpowered device.

What is the maximum capacitive load this device can drive reliably?

Based on dynamic characteristics and output drive capability, 74LVC2G02GF,115 reliably drives ≤50 pF loads at VCC ≥ 3.0 V with tpd ≤ 6.2 ns. For heavier loads (e.g., >100 pF), propagation delay increases nonlinearly and output voltage swing degrades; use a buffer stage or reduce trace capacitance via layout optimization.

Is the XSON8 (SOT1089) package compatible with standard reflow profiles?

Yes - the SOT1089 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and supports standard lead-free reflow profiles (peak 260 °C, 10 s max). Its 0.35 mm profile and thermal pad-less design simplify stencil printing and reduce tombstoning risk compared to QFN variants.
