Nexperia USA Inc. 74LVC2G32DC,125

Overview

74LVC2G32DC,125 from Nexperia is a dual 2-input OR gate logic IC in VSSOP8 package (SOT765-1), operating from 1.65 V to 5.5 V supply, featuring 5 V-tolerant inputs, 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 space-constrained digital interfaces.

For engineers reviewing the 74LVC2G32DC,125 datasheet, 74LVC2G32DC,125 pinout, 74LVC2G32DC,125 application, or 74LVC2G32DC,125 equivalent, this device serves as a low-power, high-noise-immunity dual OR gate with verified 24 mA output drive at 3.0 V, -40 °C to +125 °C operation, and JEDEC-compliant ESD robustness (HBM >2000 V).

Technical Context

This device implements two independent OR logic functions with Schmitt-trigger inputs that accept slow-rising/falling signals without oscillation, enabling reliable interfacing with mechanical switches or noisy sensor outputs. Each gate supports rail-to-rail input voltage range up to 5.5 V regardless of VCC.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial system power-down-critical for mixed-voltage board architectures. Propagation delay ranges from 0.7 ns (at 5 V) to 8.8 ns (at 1.65 V), with guaranteed timing across full temperature range.

FAQ

Can 74LVC2G32DC,125 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device supports 5 V-tolerant inputs across its full 1.65 V–5.5 V supply range. Input voltage may reach 5.5 V regardless of VCC level, enabling true level translation without external components. This is confirmed in Table 6 (Recommended Operating Conditions) and Table 5 (Limiting Values) of the datasheet.

What is the maximum capacitive load the outputs can drive reliably?

The outputs are characterized to drive up to 50 pF load capacitance with specified propagation delay and output voltage levels, as defined in Table 10 (Test Data) under conditions including CL = 50 pF and RL = 500 Ω. Driving heavier loads increases delay and may degrade VOL/VOH margins; derating is recommended beyond 50 pF.

Does the IOFF feature require external biasing or control signals?

No. IOFF is fully automatic and requires no external configuration. When VCC drops to 0 V, the internal circuitry disables both outputs to high-impedance state, preventing current flow from powered inputs into the unpowered device. This behavior is intrinsic to the silicon design and verified in Table 7 (Static Characteristics) under IOFF leakage conditions.

Is the 74LVC2G32DC,125 RoHS compliant and halogen-free?

Yes. Nexperia confirms RoHS compliance and halogen-free status for the 74LVC2G32DC,125 per its product change notification PCN-2021-001 and material declarations published on the Nexperia website. The VSSOP8 package (SOT765-1) uses lead-free matte tin terminations and meets JEDEC J-STD-609 Class 1 requirements.
