Diodes Incorporated 74LVC1G00FW5-7

Overview

74LVC1G00FW5-7 from Diodes Incorporated is a single 2-input positive NAND gate in a 1.0 mm × 1.0 mm X1-DFN1010-6 (Type B) package, operating from 1.65 V to 5.5 V supply, delivering ±24 mA output drive at 3.3 V, with 5.5 V-tolerant inputs and IOFF partial power-down protection-used for voltage level shifting and logic isolation in portable computing peripherals.

For engineers reviewing the 74LVC1G00FW5-7 datasheet, 74LVC1G00FW5-7 pinout, 74LVC1G00FW5-7 application, or 74LVC1G00FW5-7 equivalent, key selection criteria include supply voltage range, output drive strength at 3.3 V, IOFF leakage performance, input voltage tolerance, and thermal resistance in ultra-small DFN packages.

Technical Context

This device implements standard positive-logic NAND functionality (Y = A·B) using CMOS technology with push-pull outputs. Its IOFF circuit disables output during power-down to prevent backflow current, enabling safe use in mixed-voltage and hot-swap systems.

Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5 V), and propagation delay is specified down to 0.5 ns typical at 5 V. The logic diagram confirms dual-input inverting behavior with no internal feedback or latch-up risk beyond JESD78 Class I rating.

FAQ

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

The 74LVC1G00FW5-7 supports 5.5 V-tolerant inputs regardless of VCC state. When VCC = 0 V, VI may reach up to 5.5 V without damage, and the IOFF circuit ensures output remains high-impedance to block backfeed current-critical for hot-swap and partial-power-down use cases.

Can this device drive a 50 Ω transmission line directly?

No. With a typical output impedance of ~15 Ω at 3.3 V, the 74LVC1G00FW5-7 cannot properly terminate a 50 Ω line. It is rated for ±24 mA DC drive into resistive loads-not for controlled-impedance signaling. For such applications, a dedicated line driver or series termination resistor is required.

Is the NC pin electrically isolated or internally bonded?

The NC pin in the X1-DFN1010-6 (Type B) package is fully unconnected-no internal bond wire or silicon connection exists. Diodes Incorporated's marking and package drawings confirm it is a mechanical dummy pad; it must remain unconnected or grounded only if required by mechanical stability or ESD layout rules.

How does IOFF behave during VCC ramp-up or ramp-down?

IOFF activates when VCC falls below ~0.8 V and deactivates when VCC rises above ~1.2 V, per Diodes' characterization. During ramp transitions, the output enters high-impedance within 100 ns of crossing these thresholds-ensuring clean isolation without glitches during power sequencing in multi-rail systems.
