Diodes Incorporated 74LVCE1G00FZ4

Overview

74LVCE1G00FZ4 from Diodes Incorporated is a single 2-input positive NAND gate in DFN1410 package, operating from 1.4V to 5.5V supply, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and IOFF-enabled partial power-down protection. It serves as a level-shifting logic gate in mixed-voltage digital interfaces.

For engineers reviewing the 74LVCE1G00FZ4 datasheet, 74LVCE1G00FZ4 pinout, 74LVCE1G00FZ4 application, or 74LVCE1G00FZ4 equivalent, key selection criteria include supply voltage flexibility (1.4–5.5V), 5.5V input tolerance, IOFF functionality for system power sequencing, propagation delay down to 0.6ns at 3.3V/15pF, and DFN1410 thermal performance (θJA = 430°C/W).

Technical Context

This device implements standard Boolean NAND logic (Y = A·B) with totem-pole CMOS output. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe use in hot-swap and multi-rail systems.

Input voltage tolerance up to 5.5V allows direct interfacing with 5V TTL or LVTTL signals while powered from 1.8V or 3.3V rails. Switching characteristics are characterized across VCC = 1.5V to 5.0V, with tPD as low as 0.6ns (typ.) at 3.3V/15pF load.

Key Specifications

Pinout & Package

74LVCE1G00FZ4 uses the DFN1410 (1.4mm × 1.0mm, 0.5mm pitch) package with wettable flank leads. Pin 2 and Pin 5 are internally connected (NC functionally, but electrically tied to GND/VCC respectively per layout).

FAQ

What is the maximum input voltage the 74LVCE1G00FZ4 can tolerate?

The 74LVCE1G00FZ4 accepts input voltages up to 5.5V regardless of VCC level, enabling direct connection to 5V logic sources even when powered from 1.4V–3.3V rails. This eliminates external level-shifting components in mixed-voltage designs and is verified per Absolute Maximum Ratings (VI = –0.5V to 6.5V, with functional operation up to 5.5V).

Does the 74LVCE1G00FZ4 support partial power-down mode?

Yes-the device integrates an IOFF circuit that disables the output when VCC = 0V, preventing damaging back-current flow from live inputs into a powered-down system section. This feature is fully specified per JESD78 Class II latch-up testing and is critical for hot-plug and multi-rail power sequencing applications.

What is the typical propagation delay at 3.3V supply?

At VCC = 3.3V, CL = 15pF, and TA = 25°C, the typical propagation delay (tPD) is 0.6ns with a maximum of 3.1ns. This value is measured from input transition (20%–80%) to output transition (20%–80%) under controlled load conditions defined in Figure 1 of DS32210 Rev. 2–2.

Which package variants are available for the 74LVCE1G00 series?

The 74LVCE1G00 is offered in three qualified packages: SOT25 (JEDEC TO-236AB), SOT353 (SC-70), and DFN1410 (1.4mm × 1.0mm, 0.5mm pitch). The FZ4 suffix specifically denotes the DFN1410 variant, which provides superior thermal performance (θJA = 430°C/W) and board-area efficiency for portable and high-density designs.
