NXP Semiconductors 74LVC2G00GD,125

Overview

74LVC2G00GD,125 from Nexperia is a dual 2-input NAND 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 to 5.5 V supply. It enables robust signal conditioning in mixed-voltage I/O interfaces of industrial controllers and portable embedded systems.

For engineers reviewing the 74LVC2G00GD,125 datasheet, 74LVC2G00GD,125 pinout, 74LVC2G00GD,125 application, or 74LVC2G00GD,125 equivalent, key selection criteria include its 5 V-tolerant inputs/outputs, -40 °C to +125 °C temperature range, XSON8 (SOT1116) 1.2 × 1.0 × 0.35 mm package, IOFF-enabled power sequencing, and propagation delay as low as 0.5 ns at 5.5 V.

Technical Context

This device implements two independent CMOS NAND gates with Schmitt-trigger input thresholds-enabling reliable operation with slow-rising or noisy signals-and supports bidirectional voltage translation via 5 V-tolerant I/Os while maintaining full compatibility with 1.65 V–5.5 V supplies. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

The logic function conforms to standard NAND truth table behavior (L/L→H, L/H→H, H/L→H, H/H→L), with static input thresholds defined per JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36, and dynamic performance characterized up to 4.2 ns max propagation delay over full temperature range at 5.5 V.

FAQ

Can 74LVC2G00GD,125 operate with VCC = 1.65 V while interfacing with 5 V inputs?

Yes. The device supports 5 V-tolerant inputs up to 5.5 V regardless of VCC level, including minimum 1.65 V. Input thresholds scale with VCC (e.g., VIH ≥ 0.65×VCC), ensuring correct logic interpretation even at lowest supply. This enables true bidirectional level translation without external biasing.

What is the maximum capacitive load this device can drive reliably at 3.3 V?

At VCC = 3.3 V and Tamb = 25 °C, the device delivers ±24 mA output drive, supporting up to ~50 pF load capacitance with ≤4.3 ns propagation delay (per Table 8). For heavier loads (>60 pF), output rise/fall times increase linearly; derating is recommended above 30 pF for timing-critical paths.

Does the IOFF feature require external pull-up/down resistors?

No. IOFF is fully internal and activates automatically when VCC = 0 V. Outputs enter high-impedance state with leakage ≤±2 μA, eliminating need for external resistors. This protects downstream circuits during hot-swap or partial power-down without adding passive components or layout complexity.

How does Schmitt-trigger action improve noise immunity in real-world applications?

Schmitt-trigger inputs provide ≥0.3 V hysteresis (typical), meaning the rising threshold (VIH) and falling threshold (VIL) differ significantly. This prevents multiple toggles on slow or noisy edges-such as those from mechanical switches or long PCB traces-ensuring one clean transition per input event in industrial control and automotive environments.
