74LVCE1G126FZ4-7

Overview

The 74LVCE1G126FZ4-7 is a single non-inverting buffer with 3-state output from Diodes Incorporated. It operates within a supply voltage range of 1.4V to 5.5V and features inputs tolerant to 5.5V for mixed-voltage environments. The device supports partial power-down applications via IOFF circuitry, which disables the output to prevent damaging current backflow when powered down. It offers ±24mA output drive at 3.3V and includes ESD protection exceeding 200V Machine Model and 2000V Human Body Model standards.

Feature Summary

• Single non-inverting buffer with 3-state output
• IOFF circuitry prevents damaging current backflow during partial power-down
• Inputs accept up to 5.5V for mixed-voltage compatibility
• ESD protection exceeds 200V Machine Model and 2000V Human Body Model

Applications

• Voltage level shifting
• Bus driver or repeater
• Power down signal isolation
• General purpose logic in portable devices

Procurement Notes

Verify the package code FZ4 corresponds to the DFN1410 footprint before procurement. Confirm that the -7 suffix indicates tape and reel packaging with a quantity of 5000 units. Ensure the design accommodates the specific thermal resistance values for the DFN1410 package under expected operating conditions.

Selection Notes

Select this component when a single-channel buffer with high-impedance control is required in mixed-voltage systems. The extended 1.4V to 5.5V supply range allows operation across various low-power logic families. The IOFF feature makes it suitable for battery-powered applications requiring efficient power management during sleep modes.

Part Context

This part belongs to the 74LVCE1G series of low-voltage CMOS logic devices. It shares functional similarities with other single-buffer gates but is distinguished by its enhanced speed characteristics and robust input tolerance. The DFN1410 package provides a compact surface-mount solution suitable for space-constrained PCB layouts.

Replacement Considerations

Direct substitutes include 74LVCE1G126W5-7 (SOT25) and 74LVCE1G126SE-7 (SOT353). These alternatives offer identical electrical performance but differ in physical package dimensions and pinout orientation. Verify board space and soldering requirements when considering package changes.
