Diodes Incorporated 74LVC2G04FZ4-7

Overview

74LVC2G04FZ4-7 from Diodes Incorporated is a dual CMOS inverter gate in X2-DFN1410-6 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and IOFF partial power-down protection. It delivers ±24mA output drive at 3.0V and supports voltage level shifting in mixed-voltage digital interfaces such as USB peripheral control and I²C signal conditioning.

For engineers reviewing the 74LVC2G04FZ4-7 datasheet, 74LVC2G04FZ4-7 pinout, 74LVC2G04FZ4-7 application, or 74LVC2G04FZ4-7 equivalent, key selection criteria include its 1.4mm × 1.0mm chip-scale footprint, sub-4ns propagation delay at 5V, IOFF-enabled isolation during system sleep states, and compatibility with 1.8V/3.3V/5V logic domains without external level shifters.

Technical Context

This device implements two independent inverting logic gates with push-pull outputs and no internal pull-ups or pull-downs. Its IOFF circuit actively disables both outputs when VCC = 0V, blocking reverse current flow up to ±10μA at 5.5V - critical for hot-swap and multi-rail power sequencing.

Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), enabling reliable interfacing across supply voltages. Propagation delay is specified down to 0.5ns minimum and 3.8ns maximum at 5V/125°C with 50pF load, supporting high-speed control signaling in portable and embedded systems.

FAQ

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

When VCC = 0V, the absolute maximum input voltage is −0.5V to +6.5V per the datasheet's Absolute Maximum Ratings table. However, with IOFF enabled, input pins are protected against backfeed; sustained 5.5V inputs are safe due to internal clamp diodes rated for 2kV HBM and 1kV CDM ESD.

Does 74LVC2G04FZ4-7 require external pull-up resistors on its outputs?

No. The device features true push-pull outputs with no internal pull-ups. External pull-ups are unnecessary unless interfacing with open-drain buses like I²C - in which case the inverter must be placed upstream of the bus, not on the bus itself, to avoid contention.

Can this device operate reliably at 1.65V supply with full 24mA drive capability?

No. The ±24mA output drive is specified only at VCC = 3.0V. At 1.65V, the guaranteed output current drops to ±4mA (IOL/IOH = ±4mA), and propagation delay increases to 8.0ns max. Full drive strength requires ≥3.0V supply.

Is the X2-DFN1410-6 package compatible with standard reflow profiles for lead-free soldering?

Yes. The package has moisture sensitivity level 1 per J-STD-020 and is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C. NiPdAu terminal finish ensures robust solder wetting and intermetallic formation under typical 60–90 second time-above-liquidus conditions.
