74LVCE1G126W5-7

Overview

The 74LVCE1G126W5-7 is a single non-inverting buffer with a 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 outputs to prevent damaging current backflow when powered down. It offers switching speed characterized at 1.5V and provides an output drive capability of ±24mA at 3.3V.

Feature Summary

• Features extended supply voltage operation from 1.4V to 5.5V
• Includes IOFF circuitry to support partial-power-down mode
• Provides high input tolerance up to 5.5V for mixed-voltage compatibility

Applications

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

Procurement Notes

Verify the specific package code W5 corresponds to the SOT25 form factor before procurement. Confirm that the -7 suffix indicates tape and reel packaging with a quantity of 3000 units per reel. Ensure the application environment remains within the recommended operating temperature range of -40°C to 85°C to maintain specified electrical characteristics.

Selection Notes

Select this component when a single-channel buffer with 3-state control is required in low-voltage designs. The LVCE series offers improved speed over standard LVC devices at 1.8V. Consider the SOT25 package for space-constrained surface-mount layouts. Verify that the 5.5V input tolerance meets the requirements of interfacing with higher voltage logic levels.

Part Context

This part belongs to the 74LVCE1G series of single-function logic ICs produced by Diodes Incorporated. It is categorized under buffers and line drivers within the broader logic integrated circuit family. The device utilizes CMOS technology to achieve low power consumption while maintaining robust drive capabilities suitable for portable and general-purpose electronic systems.

Replacement Considerations

The 74LVCE1G126SE-7 serves as a direct functional substitute utilizing the SOT353 package instead of SOT25. Designers must verify pinout compatibility and physical footprint differences when swapping between these package variants. Other members of the 74LVCE1G family may offer similar electrical performance but require separate verification of package dimensions.
