NXP Semiconductors 74LVC2G08GM,125

Overview

74LVC2G08GM,125 from Nexperia is a dual 2-input AND gate logic IC designed for level translation between 3.3 V and 5 V systems, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operation across 1.65 V–5.5 V supply. It enables reliable signal gating in mixed-voltage digital interfaces such as I²C buffer stages and microcontroller GPIO expansion.

For engineers reviewing the 74LVC2G08GM,125 datasheet, 74LVC2G08GM,125 pinout, 74LVC2G08GM,125 application, or 74LVC2G08GM,125 equivalent, this device serves as a low-power, voltage-tolerant combinational logic element with verified 5 V input tolerance, -40 °C to +125 °C operation, and XQFN8 (SOT902-2) package compatibility - critical for space-constrained industrial control and portable embedded designs.

Technical Context

This device implements two independent AND gates in a single monolithic CMOS structure, each with Schmitt-trigger inputs enabling robust handling of slow-rising signals and high noise immunity. The IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

It supports bidirectional voltage translation: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), while outputs drive 5 V TTL-compatible loads. Propagation delay ranges from 0.5 ns (at 5 V) to 11.3 ns (at 1.65 V, -40 °C to +85 °C), with static VIH/VIL thresholds scaling with supply voltage per JEDEC standards JESD8-7/5/B.

FAQ

Is the 74LVC2G08GM,125 pin-compatible with other 74LVC2G08 variants?

Yes - all 74LVC2G08 variants share identical logic functionality and pin assignment (1A, 1B, 1Y, VCC, GND, 2A, 2B, 2Y), though physical package dimensions and thermal characteristics differ. The GM variant uses SOT902-2 (XQFN8), requiring specific land pattern and reflow profile versus TSSOP8 or VSSOP8 versions.

Can the 74LVC2G08GM,125 be used with a 1.8 V supply and 5 V inputs?

Yes - its inputs are overvoltage tolerant up to 5.5 V independent of VCC, allowing safe interfacing with 5 V signals while powered from 1.8 V. Output voltage swing remains rail-to-rail (0 V to 1.8 V), so external level shifting is required if driving 5 V loads.

What is the role of the exposed thermal pad on the XQFN8 package?

The exposed pad (pin 9, not electrically connected) provides mechanical stability and enhances thermal dissipation. It must be soldered to a PCB copper pour tied to GND for optimal thermal performance and mechanical reliability - especially critical at ≥24 mA output drive levels.

Does the IOFF feature require external circuitry to activate?

No - IOFF is fully automatic and internal. When VCC drops to 0 V, the IOFF circuitry disables both outputs regardless of input states, blocking current flow. No enable/disable pin or external bias is needed; it functions inherently during power-down or hot-swap events.
