Diodes Incorporated 74LVC2G02RA3-7

Overview

74LVC2G02RA3-7 from Diodes Incorporated is a dual 2-input NOR gate logic IC in X2-DFN1210-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with IOFF-enabled partial power-down isolation and Schmitt-trigger inputs (100mV typical hysteresis at 3.0V). It enables voltage-level shifting and signal isolation in space-constrained portable electronics.

For engineers reviewing the 74LVC2G02RA3-7 datasheet, 74LVC2G02RA3-7 pinout, 74LVC2G02RA3-7 application, or 74LVC2G02RA3-7 equivalent, key selection criteria include its 1.2mm × 1.0mm DFN footprint, IOFF leakage <±10μA at 5.5V, propagation delay as low as 0.6ns (typ) at 5V, and guaranteed operation across –40°C to +125°C ambient.

Technical Context

This device implements two independent positive-logic NOR gates (Y = A + B) with push-pull CMOS outputs. Each gate accepts input voltages up to 5.5V regardless of VCC, enabling robust level translation between mixed-voltage domains.

The integrated IOFF circuit disables both outputs when VCC = 0V, blocking reverse current flow (>±50mA clamp rating), while Schmitt-trigger inputs tolerate slow-rising/falling signals-critical for noise-prone board interconnects and legacy interface bridging.

FAQ

Can 74LVC2G02RA3-7 operate with VCC = 1.65V while accepting 3.3V inputs?

Yes. Inputs tolerate up to 5.5V regardless of VCC level, per datasheet Recommended Operating Conditions. At VCC = 1.65V, VIH is 0.65 × VCC = 1.07V and VIL is 0.35 × VCC = 0.58V, ensuring clean recognition of 3.3V logic highs and lows without level shifters.

What is the maximum capacitive load this device can drive at 3.3V with 5ns rise time?

At VCC = 3.3V and IOH/IOL = ±24mA, the device drives ≤30pF loads within specified tpd and VOH/VOL limits. For 5ns rise time, total load (including trace + pin capacitance) must remain ≤25pF to maintain signal integrity-verified by switching characteristics table at 3.3V ±0.3V.

Does the X2-DFN1210-8 package require solder paste stencil aperture reduction for reliability?

Yes. Diodes' recommended pad layout specifies 0.15mm X and Y dimensions for the 0.3mm-pitch terminals. Stencil aperture should be reduced to 85–90% of pad size (e.g., 0.13mm × 0.13mm) to prevent bridging, per IPC-7525 guidelines for 0.3mm pitch DFNs.

How does IOFF behavior differ from standard CMOS high-impedance state?

IOFF actively disables output transistors when VCC = 0V, limiting leakage to ±10μA max-even if inputs or outputs are biased to 5.5V. Standard CMOS tri-state relies on control signals and fails catastrophically if VCC is removed while I/O remains energized, risking latch-up or damage.
