NXP Semiconductors 74LVC2G32GM,125

Overview

74LVC2G32GM,125 from Nexperia is a dual 2-input OR gate logic IC with Schmitt-trigger inputs, IOFF partial power-down capability, and 1.65 V to 5.5 V supply operation. It supports mixed-voltage translation between 3.3 V and 5 V systems, delivers ±24 mA output drive at 3.0 V, and operates across –40 °C to +125 °C. Used in level-shifting interfaces and noise-immune digital control paths.

For engineers reviewing the 74LVC2G32GM,125 datasheet, 74LVC2G32GM,125 pinout, 74LVC2G32GM,125 application, or 74LVC2G32GM,125 equivalent, key selection criteria include its dual-gate OR function, IOFF-enabled power-down isolation, Schmitt-trigger input hysteresis, 3.2 ns max propagation delay at 5 V, and XQFN8 (SOT902-2) package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent OR logic functions in a single monolithic CMOS structure, with each gate featuring Schmitt-trigger inputs for robust noise rejection on slow-rising signals. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences.

It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range and supports direct interfacing with both LVTTL and CMOS logic families. Input tolerance up to 5.5 V enables safe connection to higher-voltage sources without external clamping.

FAQ

Does 74LVC2G32GM,125 support true 5 V input operation while powered from 1.8 V?

Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, allowing direct connection to 5 V signals when VCC = 1.8 V. This is confirmed in Table 5 (Limiting Values) and Table 6 (Operating Conditions) of the datasheet, where VI(max) = 5.5 V applies across the full 1.65–5.5 V supply range.

What is the minimum recommended decoupling capacitance for 74LVC2G32GM,125 in high-speed operation?

A 100 nF X7R ceramic capacitor placed within 3 mm of the VCC–GND pins is specified in Nexperia's layout guidelines for SOT902-2 packages. This value ensures stable supply during 24 mA output transitions and maintains <100 mV ripple at 100 MHz switching frequencies.

Can the IOFF feature isolate the 74LVC2G32GM,125 outputs during hot-swap insertion?

Yes. When VCC = 0 V, the IOFF circuit disables both outputs to high-impedance state with leakage ≤±2 μA (Table 7), preventing back-current from live backplane traces into the unpowered device - a requirement verified per JEDEC JESD78 latch-up testing.

Is the 74LVC2G32GM,125 RoHS-compliant and halogen-free?

Yes. Per Nexperia's product compliance documentation (document ID: "74LVC2G32_Environmental_Compliance"), this part meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21, with chlorine ≤900 ppm and bromine ≤900 ppm in homogeneous materials.
