Nexperia USA Inc. 74LVC2G02DC,125

Overview

74LVC2G02DC,125 from Nexperia is a dual 2-input NOR gate logic IC in VSSOP8 package (SOT765-1), operating from 1.65 V to 5.5 V supply, featuring 5 V-tolerant inputs/outputs, ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V domains in compact portable and industrial control interfaces.

For engineers reviewing the 74LVC2G02DC,125 datasheet, 74LVC2G02DC,125 pinout, 74LVC2G02DC,125 application, or 74LVC2G02DC,125 equivalent, key selection criteria include mixed-voltage interface capability, guaranteed operation up to +125 °C, low dynamic power (14 pF CPD), IOFF-enabled hot-swap safety, and VSSOP8 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements two independent CMOS NOR gates with rail-to-rail input voltage tolerance up to 5.5 V and full 5 V logic compatibility, enabling direct interfacing with TTL and legacy 5 V systems while powered from 1.65–3.3 V rails. The IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), allowing robust operation with slow-rising signals from mechanical switches or RC networks. Propagation delay ranges from 0.6 ns (VCC = 5.5 V) to 11.2 ns (VCC = 1.65 V, -40 °C to +125 °C), supporting both high-speed control and low-power timing functions.

FAQ

Can 74LVC2G02DC,125 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device is explicitly rated for 5.5 V overvoltage-tolerant inputs across its full 1.65–5.5 V supply range. At VCC = 1.65 V, VIH is 0.65 × VCC = 1.07 V and VIL is 0.35 × VCC = 0.58 V, ensuring reliable recognition of 5 V logic highs via internal clamping diodes - no external components needed.

Does the IOFF feature protect against backfeed when only one supply rail is powered down?

Yes. When VCC = 0 V, the IOFF circuit disables both outputs (1Y and 2Y), limiting leakage to ±2 μA maximum. This prevents damaging reverse current flow from live 5 V buses into the unpowered IC, satisfying IEC 61000-4-2 and JEDEC JESD78 latch-up immunity requirements for partial power-down systems.

What is the maximum capacitive load the 74LVC2G02DC,125 can drive at 10 MHz?

At VCC = 3.3 V and 10 MHz toggle rate, dynamic power is calculated as PD = CPD × VCC² × f × N = 14 pF × (3.3 V)² × 10 MHz × 2 = ~3.0 mW per gate. With typical output impedance <10 Ω, it reliably drives ≤50 pF loads (including trace + probe capacitance) while maintaining tPLH/tPHL < 5 ns - verified per Figure 5 test conditions.

Is the VSSOP8 package (SOT765-1) compatible with standard reflow profiles for lead-free assembly?

Yes. The SOT765-1 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1), with peak reflow temperature up to 260 °C. Its 2.3 mm body width and 0.5 mm pitch meet standard stencil design rules; recommended profile uses ramp-to-spike ≤3 °C/s, peak 235–245 °C for 40–80 s, and cooling rate ≤6 °C/s.
