74LVCE1G126SE-7

Overview

The 74LVCE1G126SE-7 is a single non-inverting buffer with 3-state output manufactured by 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 is housed in an SOT-353 package.

Feature Summary

• Features extended supply voltage operation from 1.4V to 5.5V
• Includes IOFF circuitry to support partial-power-down mode
• Provides high ESD protection exceeding 2000-V Human Body Model

Applications

• Voltage level shifting
• Bus driver or repeater circuits
• Power down signal isolation
• General purpose logic applications

Procurement Notes

Verify that the component matches the specified SOT-353 package configuration. Confirm the presence of the -7 suffix indicates tape and reel packaging. Ensure the manufacturer is Diodes Incorporated and check RoHS compliance status against current regulatory requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring low power consumption and direct interface with TTL levels. It is suitable for portable devices such as PDAs, cell phones, and navigation systems. Consider its speed improvement over LVC technology at 1.8V when optimizing for performance in mixed-voltage environments.

Part Context

This part belongs to the 74LVCE1G series of single-function logic ICs. It is designed for use in various consumer electronics including PCs, networking equipment, and multimedia devices like DVD players and cameras. The series offers multiple package options including SOT25, SOT353, and DFN1410.

Replacement Considerations

Check datasheets for other 74LVCE1G126 variants with different package codes (e.g., W5 for SOT25) if physical footprint changes are acceptable.
