Diodes Incorporated 74LVC1G04FZ4-7

Overview

74LVC1G04FZ4-7 from Diodes Incorporated is a single CMOS inverter gate with push-pull output, designed for 1.65V–5.5V operation and 5.5V-tolerant inputs. It delivers ±24mA drive at 3.3V, supports partial power-down via IOFF, and is packaged in a 1.4mm × 1.0mm X2-DFN1410-6 leadless package for space-constrained logic interfacing in portable electronics.

For engineers reviewing the 74LVC1G04FZ4-7 datasheet, 74LVC1G04FZ4-7 pinout, 74LVC1G04FZ4-7 application, or 74LVC1G04FZ4-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 5.5V input tolerance for mixed-voltage systems, IOFF-enabled power-down isolation, propagation delay ≤5.5ns at 3.3V, and ultra-small DFN footprint compatibility with high-density PCB layouts.

Technical Context

This device implements a single positive-logic inverter (Y = A̅) with rail-to-rail CMOS output swing and TTL-level input compatibility. Its IOFF circuit actively disables output leakage during power-down, preventing backflow current when VCC = 0V while inputs remain biased.

Input thresholds scale with VCC (e.g., VIH ≥ 0.7×VCC at 4.5–5.5V), ensuring robust noise margins across supply voltages. Propagation delay is specified from 0.5ns (5V) to 7.5ns (1.8V), with typical tPD = 2.0ns at 3.3V, supporting high-speed signal inversion in timing-critical paths.

FAQ

Can 74LVC1G04FZ4-7 operate reliably at 1.65V supply?

Yes. The device is fully characterized from 1.65V to 5.5V, with guaranteed propagation delay ≤7.5ns and output drive ≥±4mA at 1.65V. Input thresholds scale accordingly (VIH ≥ 0.65×VCC), ensuring correct logic interpretation across the entire range.

What is the thermal resistance (θJA) of the X2-DFN1410-6 package?

The junction-to-ambient thermal resistance is 460°C/W under standard JEDEC test conditions (FR-4 board, 2oz copper, minimum recommended pad layout). This value assumes no additional thermal vias; adding 4–6 thermal vias beneath the exposed pad reduces θJA by ~30–50%.

How does IOFF protect the device during partial power-down?

When VCC = 0V, the IOFF circuit disables both output FETs, limiting output leakage to ±10μA even if input or output pins are pulled to 5.5V. This prevents damaging reverse current flow into a powered-down subsystem, preserving signal integrity and system reliability.

Is the X2-DFN1410-6 package RoHS and halogen-free compliant?

Yes. The 74LVC1G04FZ4-7 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free ("Green" per Diodes Inc. definition: Br+Cl <1500ppm, Sb <1000ppm), certified for use in environmentally regulated end equipment.
