Diodes Incorporated 74LVC1G02FW5-7

Overview

74LVC1G02FW5-7 from Diodes Incorporated is a single 2-input positive NOR gate in a 1.0 mm × 1.0 mm X1-DFN1010-6 (Type B) package, operating from 1.65 V to 5.5 V with ±24 mA output drive at 3.3 V, 5.5 V-tolerant inputs, and IOFF-enabled partial power-down protection. It serves as a level-shifting logic gate in compact portable electronics.

For engineers reviewing the 74LVC1G02FW5-7 datasheet, 74LVC1G02FW5-7 pinout, 74LVC1G02FW5-7 application, or 74LVC1G02FW5-7 equivalent, key selection criteria include supply voltage flexibility, 5.5 V input tolerance for mixed-voltage interfacing, IOFF current-blocking behavior during power-down, and ultra-small DFN footprint for space-constrained PCB layouts.

Technical Context

This device implements the Boolean function Y = A + B (positive NOR), with push-pull CMOS output stage and rail-to-rail input voltage range up to 5.5 V independent of VCC. Its IOFF circuit actively disables output terminals when VCC = 0 V, preventing back-current flow into powered-down subsystems.

Propagation delay ranges from 0.5 ns (min) to 6.0 ns (max) at 3.3 V across –40°C to +125°C, and input transition rate support reaches 10 ns/V at 3.3 V - enabling reliable operation in high-speed digital control paths with fast edge rates.

FAQ

What is the maximum allowable input voltage when VCC = 1.65 V?

The absolute maximum input voltage is 5.5 V regardless of VCC level, per the datasheet's Absolute Maximum Ratings table. This allows safe interfacing with 3.3 V or 5 V signals even when the device is powered from 1.65 V, eliminating external clamping components in mixed-voltage designs.

Does the NC pin on the X1-DFN1010-6 (Type B) package require grounding or floating?

The NC pin is unconnected internally and must remain electrically floating - no soldering, grounding, or routing is permitted. The datasheet explicitly defines it as "No Connection", and connecting it risks shorting adjacent terminals due to the 0.35 mm pad pitch and fine-pitch layout constraints.

How does IOFF behavior affect system-level power-down sequencing?

When VCC drops to 0 V, the IOFF circuit disables both output and input paths, limiting leakage current to ±200 μA max. This prevents back-current from other powered rails through the NOR gate's output or inputs - ensuring clean, isolated power-down of subsystems without unintended biasing or latch-up risk.

Can this device drive a 50 pF capacitive load at 10 MHz while maintaining logic integrity?

Yes - the typical power dissipation capacitance (Cpd) is 14 pF at 10 MHz, and propagation delay remains ≤6.0 ns at 3.3 V with 30 pF load. Driving 50 pF increases dynamic current but stays within ±24 mA output capability; verified switching waveforms in the datasheet confirm clean edges under these conditions.
