Nexperia USA Inc. 74LVC2G38DP,125

Overview

74LVC2G38DP,125 from Nexperia is a dual 2-input NAND gate with open-drain outputs, designed for level translation between 3.3 V and 5 V logic domains in mixed-voltage systems. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operates across -40 °C to +125 °C. Used in I²C bus pull-up control, GPIO expansion interfaces, and voltage-level adaptive logic buffering.

For engineers reviewing the 74LVC2G38DP,125 datasheet, 74LVC2G38DP,125 pinout, 74LVC2G38DP,125 application, or 74LVC2G38DP,125 equivalent, this device serves as a robust, low-power logic translator with verified 5 V-tolerant inputs, open-drain flexibility for wired-AND configurations, and JEDEC-compliant ESD robustness (HBM >2000 V).

Technical Context

The 74LVC2G38DP,125 implements two independent NAND gates with open-drain outputs, enabling wired-logic interconnection and bidirectional bus interfacing. Each gate accepts inputs up to 5.5 V while operating from 1.65 V to 5.5 V supply, supporting mixed-voltage system integration without external level shifters.

Schmitt-trigger input thresholds provide hysteresis (typ. 0.3–0.5 V) to tolerate slow-rising signals, and the IOFF circuit actively disables outputs during power-down to prevent backflow current-critical for hot-swap and partial-power-down architectures.

FAQ

Can 74LVC2G38DP,125 be used as a level shifter between 1.8 V and 5 V logic?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, and it operates down to 1.65 V. When powered at 1.8 V, it correctly interprets 5 V inputs as HIGH and drives open-drain outputs compatible with 5 V pull-ups. No external components are needed for unidirectional 5 V → 1.8 V translation.

What is the maximum capacitive load the 74LVC2G38DP,125 can drive on its open-drain outputs?

At VCC = 3.3 V and IO = 24 mA, VOL ≤ 0.55 V into a 30–50 pF load (per datasheet test conditions). For reliable I²C operation (400 kHz, 400 pF bus), use an external pull-up resistor ≤2.2 kΩ to maintain rise time <1 μs and ensure VOL stays below 0.4 V.

Does the IOFF feature work when only one supply rail is powered down?

Yes - IOFF activates whenever VCC = 0 V, regardless of input/output voltage states. Inputs and outputs enter high-impedance mode, limiting leakage to ±2 μA even if 5 V signals remain applied. This protects downstream circuitry during partial system power cycling.

Is the 74LVC2G38DP,125 suitable for automotive applications?

No - although rated for -40 °C to +125 °C, it is not AEC-Q200 qualified and lacks automotive-specific stress testing, failure-in-time (FIT) data, or PPAP documentation. Use only in non-safety-critical industrial or consumer systems unless explicitly validated by the end customer.
