Diodes Incorporated 74LVC2G00HD4-7

Overview

74LVC2G00HD4-7 from Diodes Incorporated is a dual 2-input NAND gate in X2-DFN2010-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with IOFF-enabled partial power-down protection and Schmitt-trigger inputs (100mV hysteresis at 3.0V). It enables voltage-level shifting and signal isolation in space-constrained portable electronics.

For engineers reviewing the 74LVC2G00HD4-7 datasheet, 74LVC2G00HD4-7 pinout, 74LVC2G00HD4-7 application, or 74LVC2G00HD4-7 equivalent, key selection criteria include its dual-gate logic function, 1.95mm × 1.0mm DFN footprint, IOFF leakage <±10μA at 5.5V, and guaranteed 4.3ns propagation delay at 3.3V/25°C - critical for low-voltage interface integrity and power-gated system design.

Technical Context

This device implements two independent positive-logic NAND gates (Y = A·B) with push-pull CMOS outputs. Each input features Schmitt-trigger action (100mV typical hysteresis at VCC = 3.0V), enabling robust operation with slow-rising/falling signals across the full 1.65–5.5V supply range.

The IOFF circuit actively disables outputs during power-down, limiting backflow current to <±10μA when VCC = 0V and VI/VO = 5.5V. Input tolerance extends to 5.5V regardless of VCC, supporting mixed-voltage interfacing without external level shifters.

FAQ

Can 74LVC2G00HD4-7 operate with VCC = 1.65V while driving a 15pF load at 10MHz?

Yes. At VCC = 1.65V, the device delivers ≥4mA sink/source current and exhibits 8.6ns max propagation delay (TA ≤ +85°C), supporting reliable 10MHz toggle with 15pF load. Its CMOS architecture ensures rail-to-rail output swing and sub-10μA ICC at this voltage, making it suitable for ultra-low-power wake-up logic.

What is the maximum allowable input voltage when VCC = 0V?

The absolute maximum input voltage is −0.5V to +6.5V regardless of VCC state. With VCC = 0V, inputs tolerate up to +5.5V per datasheet Note 7, and IOFF limits input-to-output leakage to ±10μA - enabling safe "live insertion" into partially powered systems without risk of latch-up or damage.

Does the X2-DFN2010-8 package require solder paste stencil aperture reduction for reliable reflow?

Yes. Diodes Incorporated recommends a 0.125mm-thick stencil with 80% area ratio apertures (0.25mm × 0.35mm) for the 0.5mm-pitch leads and thermal pad. This prevents bridging and ensures coplanar wetting of all eight terminals, especially critical given the 0.4mm profile and absence of gull-wing leads for visual inspection.

How does the Schmitt-trigger input affect timing analysis in synchronous circuits?

The 100mV hysteresis introduces deterministic input threshold asymmetry (VIH ≈ 2.0V, VIL ≈ 1.9V at VCC = 3.0V), eliminating metastability from slow edges. Unlike standard CMOS inputs, it guarantees clean transitions even with 100ns rise times - simplifying setup/hold validation and removing need for external RC filters in clock-enable or interrupt paths.
