Diodes Incorporated 74LVC1G07FW4-7

Overview

74LVC1G07FW4-7 from Diodes Incorporated is a single non-inverting buffer with open-drain output, designed for voltage-level shifting and signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, supports IOFF partial power-down mode, delivers up to 32mA sink current at 4.5V, and is packaged in X2-DFN1010-6 (1.0mm × 1.0mm, 0.39mm height).

For engineers reviewing the 74LVC1G07FW4-7 datasheet, 74LVC1G07FW4-7 pinout, 74LVC1G07FW4-7 application, or 74LVC1G07FW4-7 equivalent, key selection criteria include open-drain drive capability, 5.5V-tolerant inputs, IOFF-enabled power-down isolation, and compact DFN packaging for space-constrained logic interfacing.

Technical Context

This device implements a CMOS-based single-buffer architecture with an open-drain output stage, enabling wired-OR/AND logic functions when multiple outputs share a common pull-up. Its IOFF circuit actively disables output leakage during power-down, preventing backflow currents in partially powered systems.

The input threshold is VCC-dependent (e.g., VIH = 0.7×VCC at 4.5–5.5V), and propagation delay ranges from 0.5ns (min) to 4.0ns (max) at 3.3V across –40°C to +85°C, supporting high-speed level translation in portable and embedded interfaces.

FAQ

Can 74LVC1G07FW4-7 drive a 5V pull-up resistor directly?

Yes - its 5.5V-tolerant inputs and open-drain output allow direct connection to a 5V pull-up. The output will sink current when active, pulling the line low; when inactive, the external pull-up returns the line high. No level-shifting components are needed, provided the load current stays within 32mA at 4.5V VCC.

What happens to the output during power-down (VCC = 0V)?

When VCC is removed, the IOFF circuit disables the output, limiting leakage to ±10μA regardless of input or output voltage (up to 5.5V). This prevents damaging back-current flow into unpowered sections of the system - a critical feature for partial-power-down architectures like those in modern laptops and docking stations.

Is the X2-DFN1010-6 package compatible with standard reflow profiles?

Yes - it is rated Moisture Sensitivity Level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard Pb-free reflow profiles (peak 260°C). Its NiPdAu terminations ensure reliable wetting and joint formation without special flux or pre-bake requirements.

How does propagation delay vary with supply voltage?

tPD decreases as VCC increases: at 1.8V it is 1.0–6.5ns, at 3.3V it is 0.5–4.0ns, and at 5.0V it is 0.5–3.0ns (min/max over –40°C to +85°C). This inverse relationship enables tighter timing margins in higher-voltage domains while maintaining functional operation down to 1.65V.
