NXP Semiconductors 74LVC1G10GV,125

Overview

74LVC1G10GV,125 from Nexperia is a single 3-input NAND gate logic IC designed for low-voltage, mixed-supply digital interfacing in space-constrained applications. It operates from 1.65 V to 5.5 V, supports 5 V-tolerant inputs, features Schmitt-trigger inputs for noise immunity, and includes IOFF circuitry for partial power-down protection. It is used in level translation, signal conditioning, and enable/control logic in portable and industrial control systems.

For engineers reviewing the 74LVC1G10GV,125 datasheet, 74LVC1G10GV,125 pinout, 74LVC1G10GV,125 application, or 74LVC1G10GV,125 equivalent, key selection criteria include input voltage tolerance (up to 5 V), IOFF-enabled power-down safety, propagation delay down to 1.0 ns at 5 V, ±24 mA output drive at 3.0 V, and operation across –40 °C to +125 °C.

Technical Context

This device implements standard CMOS 3-input NAND logic with Schmitt-trigger inputs that accept slow-rising/falling signals without oscillation. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and multi-rail system integrity.

The logic function conforms to IEEE/IEC 60617-12 and JEDEC JESD8 standards across multiple supply ranges (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V, 4.5–5.5 V). Input thresholds are dynamically scaled (e.g., VIH = 0.7VCC at 4.5–5.5 V), enabling reliable interfacing with both LVTTL and 3.3 V CMOS sources.

FAQ

Can 74LVC1G10GV,125 be used with a 1.8 V supply and 5 V input signals?

Yes. The device supports VCC as low as 1.65 V and accepts input voltages up to 5.5 V independent of supply level. This allows direct connection to 5 V sensors or microcontrollers while operating from a 1.8 V rail - no external level shifters required. Input thresholds scale with VCC (e.g., VIH = 0.7VCC at 4.5–5.5 V), ensuring correct logic interpretation.

Does 74LVC1G10GV,125 support hot-swap or partial power-down operation?

Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA maximum. This protects upstream drivers and downstream circuits during live insertion, power sequencing, or fault isolation - a key requirement in modular power architectures and FPGA I/O banks.

What is the maximum capacitive load this device can drive reliably?

At VCC = 3.3 V and Tamb = 25 °C, the device drives ≤30 pF loads with guaranteed tPLH/tPHL ≤5.0 ns (typical 2.6 ns). For heavier loads (e.g., >50 pF), propagation delay increases linearly; design margin requires verifying setup/hold times against the driven device's specifications using worst-case 4.4 ns (max) delay at 5 V.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V), rejecting noise and slow transitions that could cause multiple toggles on a single edge. This eliminates false triggering from EMI, mechanical switch bounce, or marginal comparator outputs - reducing firmware debounce overhead and improving deterministic behavior in noisy industrial environments.
