Product details
Overview
74LVC1G38GX,125 from Nexperia is a single 2-input NAND gate with open-drain output, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, ±24 mA output drive at 3.0 V, and operation across -40 °C to +125 °C. It is used in I²C bus pull-up control and mixed-voltage interface isolation.
For engineers reviewing the 74LVC1G38GX,125 datasheet, 74LVC1G38GX,125 pinout, 74LVC1G38GX,125 application, or 74LVC1G38GX,125 equivalent, this device serves as a compact, thermally enhanced logic translator in space-constrained industrial and automotive-adjacent control modules where rail-to-rail voltage compatibility and low quiescent current (<4 μA) are critical.
Technical Context
The 74LVC1G38GX implements standard NAND logic with open-drain output, requiring an external pull-up resistor to define high-level voltage. Its Schmitt-trigger inputs accept slow-rising signals (≤10 ns/V transition rate) and tolerate input voltages up to 5.5 V regardless of VCC (1.65–5.5 V), enabling direct interfacing with TTL and 5 V CMOS outputs.
IOFF functionality disables the output when VCC = 0 V, blocking backflow current during hot insertion or partial system shutdown. The X2SON5 package (SOT1226-3) provides thermal enhancement via exposed die pad and side-wettable flanks-though not present in GX variant-enabling stable operation under continuous 24 mA sink loads at elevated ambient temperatures.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G00GV | Push-pull (not open-drain) output; identical supply range and Schmitt inputs | Cannot perform wired-AND or I²C-style bus sharing; unsuitable for shared-bus applications | Select when driving CMOS loads directly without external pull-up; avoid for bus arbitration or level translation |
| SN74LVC1G38DBVR | Same logic function and open-drain output; SOT-23-5 package (larger footprint, lower thermal resistance) | Better power dissipation margin at 32 mA sink; less suitable for ultra-dense PCB layouts | Prefer for prototyping or higher-current designs where X2SON5 rework is impractical; same electrical behavior |
Compared with 74LVC1G38GX,125, the 74LVC1G00GV lacks bus-sharing capability due to push-pull output, while SN74LVC1G38DBVR offers identical logic but trades miniaturization for thermal headroom and assembly simplicity.

FAQ
What is the maximum sink current capability of the 74LVC1G38GX,125 at 3.3 V supply?
The 74LVC1G38GX,125 delivers up to 24 mA sink current at VCC = 3.0 V with VOL ≤ 0.55 V, and maintains 32 mA capability at VCC = 4.5 V with VOL ≤ 0.55 V. These values are specified across -40 °C to +125 °C and validated per JEDEC JESD78.
Can the 74LVC1G38GX,125 be used without an external pull-up resistor?
No. As an open-drain device, the 74LVC1G38GX,125 cannot drive a HIGH logic level internally. An external pull-up resistor to a defined voltage rail (e.g., 3.3 V or 5 V) is mandatory to establish the HIGH state on the Y output pin.
Does the 74LVC1G38GX,125 support hot insertion or partial power-down operation?
Yes. Its IOFF circuitry actively disables the output and blocks backflow current when VCC = 0 V, meeting JEDEC JESD78 requirements for partial power-down. This allows safe insertion into live backplanes or operation in systems with staggered power sequencing.
How does the Schmitt-trigger input improve noise immunity in real-world applications?
Schmitt-trigger inputs provide hysteresis (typically ~0.3 V at 3.3 V), rejecting noise spikes smaller than the threshold gap and preventing false toggling on slow or noisy signals-critical for long-trace industrial wiring or unshielded automotive switch inputs.
