Nexperia USA Inc. 74LVC1G38GF,132

Overview

74LVC1G38GF,132 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 partial power-down protection, and operates across 1.65 V to 5.5 V supply. Used in bus arbitration, I²C pull-up control, and mixed-voltage interface circuits.

For engineers reviewing the 74LVC1G38GF,132 datasheet, 74LVC1G38GF,132 pinout, 74LVC1G38GF,132 application, or 74LVC1G38GF,132 equivalent, this device serves as a compact, temperature-stable (–40 °C to +125 °C) logic translator with ±24 mA sink capability at 3.0 V, 5 V-tolerant inputs, and JEDEC-compliant ESD robustness (HBM >2000 V).

Technical Context

This device implements a standard NAND Boolean function (Y = NOT(A AND B)) with open-drain output requiring an external pull-up resistor. Its Schmitt-trigger inputs accept slow-rising signals and reject noise up to ±0.35 × VCC hysteresis, enabling reliable operation in noisy industrial environments.

The IOFF circuit actively disables the output when VCC = 0 V, blocking backflow current and supporting hot-swap and partial power-down systems. Input voltage tolerance up to 5.5 V allows direct interfacing with legacy 5 V TTL outputs while powered from 1.65 V–3.3 V supplies.

FAQ

What is the maximum sink current capability of the 74LVC1G38GF,132 at 1.8 V supply?

At VCC = 1.8 V, the device guarantees a minimum sink current of 4 mA while maintaining VOL ≤ 0.45 V (per Table 7). This is sufficient to drive standard LED indicators or interface with 1.8 V logic families with typical load capacitance below 30 pF. The absolute maximum rating remains ±50 mA, but sustained operation above 8 mA at 1.8 V requires thermal derating verification.

Can the 74LVC1G38GF,132 be used without an external pull-up resistor?

No - the open-drain output requires an external pull-up resistor to define the HIGH state voltage level and provide source current. Typical values range from 1 kΩ (for fast rise times <10 ns) to 10 kΩ (for low-power I²C bus operation). Omitting the pull-up results in undefined HIGH output and functional failure.

Does the 74LVC1G38GF,132 support hot-swap operation in backplane systems?

Yes - its IOFF circuit automatically disables the output and blocks reverse current flow when VCC drops to 0 V, preventing damage during live insertion or removal. This feature is validated per JEDEC JESD78 and supports hot-swap controllers in modular computing and telecom infrastructure.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide hysteresis (≈0.35 × VCC), meaning the threshold for detecting a rising edge (VIH) is higher than for a falling edge (VIL). This prevents oscillation when input signals cross the threshold slowly or contain noise spikes, making the device robust against EMI, crosstalk, and mechanical switch bounce in industrial control applications.
