74LVC1G126SE-7

Overview

The Diodes Incorporated 74LVC1G126SE-7 is a single non-inverting buffer with 3-state output in an SOT-353 package. It operates from 1.65V to 5.5V and accepts inputs up to 5.5V. The device features IOFF circuitry for partial power-down support, preventing backflow current. Electrical characteristics include a maximum propagation delay of 6.0ns at 3.3V across the -40°C to +125°C temperature range.

Feature Summary

• Provides non-inverting buffering with high-impedance state control via the OE pin
• Integrates IOFF circuitry to disable outputs and prevent damaging current backflow during power-down
• Accepts input voltages up to 5.5V, enabling direct interface with TTL levels in mixed-voltage environments

Applications

• Voltage level shifting between different logic domains
• Power down signal isolation in multi-supply systems
• General purpose logic buffering for portable devices

Procurement Notes

Verify the SE suffix corresponds to the SOT-353 package configuration. Confirm RoHS compliance and lead-free status against the latest manufacturer documentation. Ensure the ordering code matches the required tape and reel quantity specifications for production integration.

Selection Notes

Select this component when a single-channel non-inverting buffer with 3-state capability is required. The wide supply voltage range supports operation from low-power 1.65V applications up to standard 5V logic systems. The integrated IOFF feature makes it suitable for designs requiring safe partial power-down modes.

Part Context

This part belongs to the 74LVC1G126 series of single buffers with 3-state outputs manufactured by Diodes Incorporated. The series offers various package options including SOT25, SOT553, and DFN types, all sharing the same logical function and electrical specifications while differing in physical footprint and thermal characteristics.

Replacement Considerations

Cross-reference with other manufacturers' 74LVC1G126 equivalents. Verify pinout compatibility and ensure the replacement device meets the same 5.5V input tolerance and IOFF functionality requirements.
