74LVCE1G125SE-7

Overview

The 74LVCE1G125SE-7 is a single non-inverting buffer and bus driver featuring a 3-state output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.4V to 5.5V and utilizes CMOS technology for low power consumption. The device supports partial power-down applications through dedicated I_OFF circuitry that prevents damaging current backflow when powered down. Inputs are tolerant to 5.5V, enabling direct interface with TTL levels in mixed-voltage environments. It is housed in an SOT-353 package.

Feature Summary

• Features 3-state output capability allowing high impedance states for bus driving applications
• Includes IOFF circuitry to support partial-power-down mode operation without damaging backflow
• Provides 5.5V input tolerance for compatibility in mixed voltage systems
• Offers switching speed improvements over LVC logic at 1.8V

Applications

• Voltage level shifting between different logic families
• Bus driver and repeater functions
• Power down signal isolation
• General purpose logic applications

Procurement Notes

Verify the specific ordering suffix SE corresponds to the SOT-353 package configuration required for your design. Confirm RoHS compliance status and lead-free finish requirements against current manufacturing standards. Ensure the -7 suffix matches the tape and reel packaging quantity specifications needed for your assembly process. Cross-reference the datasheet revision number to ensure all electrical characteristics align with your system constraints.

Selection Notes

Select this component when a single-channel non-inverting buffer with 3-state control is required. It is suitable for designs needing 5.5V input tolerance and operation across a wide voltage range from 1.4V to 5.5V. Consider this part for mixed-voltage interfaces where direct connection to TTL levels is necessary. The low power consumption makes it appropriate for battery-operated or energy-efficient portable devices.

Part Context

This device 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 LVCE series is designed to offer enhanced performance characteristics compared to standard LVC logic, specifically targeting low voltage applications requiring robust drive capabilities and speed improvements.

Replacement Considerations

Check for other variants within the 74LVCE1G125 family such as W5 (SOT25) or FZ4 (DFN1410) if package changes are acceptable. Verify functional equivalence with other single 3-state buffer parts from different manufacturers ensuring voltage and pinout compatibility.
