Diodes Incorporated 74LVC1G00FW4-7

Overview

74LVC1G00FW4-7 from Diodes Incorporated is a single 2-input positive NAND gate in X2-DFN1010-6 package (1.0 mm × 1.0 mm × 0.4 mm), operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.3 V, 5.5 V-tolerant inputs, and IOFF partial power-down protection. It enables voltage-level shifting and signal isolation in space-constrained portable logic interfaces.

For engineers reviewing the 74LVC1G00FW4-7 datasheet, 74LVC1G00FW4-7 pinout, 74LVC1G00FW4-7 application, or 74LVC1G00FW4-7 equivalent, key selection criteria include its 0.35 mm pad pitch DFN footprint, sub-6 ns propagation delay at 3.3 V, IOFF leakage <±10 μA, and compatibility with mixed-voltage 1.8 V/3.3 V/5 V systems.

Technical Context

This device implements standard positive-logic NAND functionality (Y = A·B) using CMOS technology with push-pull outputs. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V while inputs remain biased at up to 5.5 V.

Input thresholds are voltage-ratio-based (VIH = 0.65×VCC min at 1.65–1.95 V; 0.7×VCC at 4.5–5.5 V), ensuring reliable TTL-level interfacing across supply voltages. Propagation delay is specified from 0.5 ns (5 V) to 8.0 ns (1.8 V), with input transition rate support up to 20 ns/V at 1.8 V.

FAQ

Is the NC pin on 74LVC1G00FW4-7 required to be left floating?

Yes-the NC (No Connection) pin is internally unconnected and must remain unattached to any net, including ground or power. Soldering it to PCB copper may cause mechanical stress or unintended coupling. Diodes' package drawings explicitly prohibit connection, and doing so voids guaranteed parametric performance.

Can 74LVC1G00FW4-7 operate reliably at 1.5 V supply?

No-it is not characterized or guaranteed below 1.65 V. The datasheet specifies 1.65 V as the absolute minimum operating voltage; at 1.5 V, propagation delay increases unpredictably, output drive falls below specification, and VIH/VIL thresholds become undefined. For 1.5 V systems, consider the ALVC or AHC logic families instead.

What is the maximum capacitive load this device can drive while maintaining 6 ns tpd at 3.3 V?

At 3.3 V and TA = +25°C, the typical tpd is 2.2 ns with 30 pF load (per test condition in Figure 1). With 50 pF load (including trace and input capacitance), tpd remains within spec at ≤4.7 ns (max). Driving >50 pF will degrade timing margin and may exceed the 6.0 ns max limit at temperature extremes.

Does IOFF functionality require external pull-up/down resistors on inputs?

No-IOFF activates automatically when VCC = 0 V, regardless of input voltage (up to 5.5 V). External biasing is unnecessary and discouraged; leaving inputs floating during power-down is acceptable per datasheet Note 9, though tying unused inputs to VCC or GND is recommended for static noise immunity in active states.
